About Sunil Tanna
Hello. I am Sunil Tanna - author, software developer, and tutor (maths and science). You can find out more about me at my website, www.suniltanna.com
My first real memory of reading a book was when I was five, in infants school. The teacher was conducting a very detailed and rather slow lesson on how to tell the time. I already knew how to tell the time, or at least I thought I did, and I was bored.
The whole class was sitting on a mat, and I happened to be sitting near the back, next to a bookshelf. I took a book off the shelf about a group of school children who investigated, and eventually solved, a smuggling mystery. Completely absorbed, I sat quietly reading to myself.
I don't think it was a huge book, it couldn't have been, but I amazed myself by managing to read the entire book cover to cover. Just as I turned the last the last page, I suddenly realised that the lesson was coming to an end. I remember worrying that I might have missed some vital new detail of telling the time that perhaps the teacher had slipped in during the second half of the lesson.
Somehow however I survived. I've had a love of books ever since, although nowadays I generally try to choose more opportune moments to read them.
As a writer, I hope to write about both my personal experiences, and the things that interest me most. Since I have quite an eclectic range of interests, you can expect a diverse range of books from me in future.
I hope you enjoy reading my books, and if you do, don't forget to leave a review on Amazon.

by
Sunil Tanna
$0.99
Radians are the preferred unit that mathematicians and scientists use for measuring angles. Likewise steradians are the preferred unit used for measuring solid angles. This book explains the key concepts behind radians and steradians, as well as how to perform mathematical calculations based on these units (including many worked examples, questions for you to do yourself, and answers to those questions to check your results).
Topics covered in the book include:
* Key terminology associated with circles
* A comparison between measuring angles in degrees and other units such as gradians
* The definition of radians
* How angles can be measured in radians
* Why radians are a "natural" unit for measuring angles
* How many radians correspond to a full circle rotation, half circle rotation, and a quarter circle rotation (right angle)
* How many degrees correspond to a radian
* How to convert degrees into radians
* How to convert radians into degrees
* Conversions of some common angles between degrees and exact radian values
* How to calculate arc lengths using radians
* How to calculate sector perimeters using radians
* How to calculate sector areas using radians
* How to calculate chord lengths using radians
* How to calculate segment perimeters using radians
* How to calculate major and minor segment areas using radians
* Radians usage as an SI Unit
* Some uses of radians in physics
* Common SI Unit prefixes of radians, and subject areas where you may encounter them
* Milliradian approximations used in various militaries and in gunnery
* Dimensional analysis involving radians
* The definition of steradians
* How many steradians are in a complete sphere and in a hemisphere
* How to calculate the aperture angle of a cone of 1 steradian
* Some common applications of steradians
* Dimensional analysis involving steradians

Knowing multiplication tables is a key math skill. This is because multiplication tables are not only directly useful, but are also a foundation upon which other mathematical techniques are based – including multiplication of larger numbers, division, and fractions.
This book is a guide for parents wishing to help their kids master this important skill. It shows parents how to teach their kids in a simple step-by-step fashion, and includes numerous tips and tricks to help children remember, or work out, the answers.
Times tables from 0X0 to 12X12 are covered, and as well as the times tables themselves, the book also includes additional facts, such as common prefixes used for words relating to various numbers, how to quickly check if a number is in the 2, 3, 4, 5, 6, 9, or 10 times table, and more.

The second in a series of five books, this book tells the history of life at the start of the Mesozoic Era during the Triassic Period, which was between 252 and 201 million years ago. In this period, the first lepidosaurs (the group containing snakes and lizards) and first archosaurs (the group containing crocodiles and birds) appeared. The first dinosaurs walked the land, the first pterosaurs filled the skies, and the seas were populated by marine reptiles such as ichthyosaurs, plesiosaurs, and others.

You Can Do Math: Working With Fractions
Aug 26, 2014
by
Sunil Tanna
$0.99
This book is a complete introduction to learning, understanding, and mastering working with fractions (sometimes known as "common fractions", "simple fractions", or "vulgar fractions"), and is based on the author's personal experience providing 1:1 mathematics tuition to both school students and adult numeracy students.
Topics covered include:
* What is a fraction
* Names of fractions
* Fractions as division (converting a fraction into a division calculation and back)
* Mixed numbers
* Improper ("top heavy") fractions
* Converting mixed numbers to top heavy fractions
* Converting whole numbers to top heavy fractions
* Converting top heavy fractions to mixed numbers
* Equivalent fractions
* Simplifying fractions
* Expressing fractions in their simplest form
* Comparing fractions
* Adding fractions (including adding several fractions together)
* Subtracting fractions
* Multiplying fractions (including multiplying several fractions together)
* Simplifying fraction multiplications
* Dividing fractions
* Simplifying complex fractions (fractions within a fraction)
* How to convert fractions into decimal numbers
* How to convert decimal numbers into fractions
Every topic is explained in detail, complete with many step-by-step worked examples and diagrams. Additionally. major topics are immediately followed by a set of practice questions (there are well over 300 questions in total in the book), the answers to which can be found at the end of each chapter.
In summary, whether you want to learn fractions yourself, or teach your kids fractions, or are a student preparing for exams such as GCSEs or high school maths tests, or are an adult learner wishing to improve your numeracy and knowledge of this important math topic - this book is ideal for you.
This book has been specially prepared for use on the Kindle - including taking great care to ensure all math symbols, formulas, and calculations display correctly on the Kindle screen (many other math books do not display math symbols correctly). A color screen is recommended, but not essential - there are a couple of diagrams where the text refers to colors in the picture - but these should still be understandable even on a black and white screen.

Amazing Math: Introduction to Platonic Solids
Oct 26, 2014
by
Sunil Tanna
$1.99
This book is a guide to the 5 Platonic solids (regular tetrahedron, regular cube, regular octahedron, regular dodecahedron, and regular icosahedron). These solids are important in mathematics, in nature, and are the only 5 convex regular polyhedra that exist.
Note: Some familiarity with basic trigonometry and very basic algebra (high school level) will allow you to get the most out of this book - but in order to make this book accessible to as many people as possible, I have included a brief recap on some necessary basic concepts from trigonometry (such as sine, cosine, radians, etc.).
- What the Platonic solids are
- The history of the discovery of Platonic solids
- The common features of all Platonic solids
- The geometrical details of each Platonic solid
- Examples of where each type of Platonic solid occurs in nature
- How we know there are only five types of Platonic solid (geometric proof)
- A topological proof that there are only five types of Platonic solid
- What are dual polyhedrons
- What is the dual polyhedron for each of the Platonic solids
- The relationships between each Platonic solid and its dual polyhedron
- How to calculate angles in Platonic solids using trigonometric formulae
- The relationship between spheres and Platonic solids
- How to calculate the surface area of a Platonic solid
- How to calculate the volume of a Platonic solid
- An introduction to some other interesting types of polyhedra – prisms, antiprisms, Kepler-Poinsot polyhedra, Archimedean solids, Catalan solids, Johnson solids, and deltahedra.
Note: Some familiarity with basic trigonometry and very basic algebra (high school level) will allow you to get the most out of this book - but in order to make this book accessible to as many people as possible, I have included a brief recap on some necessary basic concepts from trigonometry (such as sine, cosine, radians, etc.).
