Blog postThe Kindle Unlimited Per-Page Rate for January, 2020 $0.004411 is the per-page rate for KENP read for Kindle Unlimited in January, 2020. It’s down from December’s rate of $0.004664, which was also down from November. It takes a dip around this time almost every year, probably an effect characteristic of the holidays. Fortunately, even after the dip, it’s still significantly above $0.004 per page.
The KDP Select Global Fund rose to a record high of $28.2 million for January, 2020. -
Blog postThe December, 2019, Kindle Unlimited Per Page Rate The Kindle Unlimited per-page rate was 0.004664 in December, 2019. It’s down from December, perhaps from holiday Kindle sales, but close to what it had been in October.
The KDP Select Global Fund rose to a new high of $26.2 million for December, 2019.

Blog postAMAZON FOUR-STAR STORE I recently visited an Amazon 4-Star store. I had no idea what to expect, other than my assumption that every product in the store was rated 4 stars or above.
(My daughter asked why they didn’t have a 5-star store. I tried to explain that it would be virtually impossible, since if a product had 49 5-star reviews and one 4-star review, it would drop the average below 5 stars.)
The first thing I realized was that it wasn’t a bookstore. There were a few boo -

Blog postThe Kindle Unlimited Per-Page Rate for November, 2019 In November, 2019, Amazon KDP paid $0.004925 (nearly $0.005) per page read for Kindle Unlimited.
This is up from October’s rate of $0.0047.
The rate is nice now (it seldom rises above $0.005). At the beginning of the year, the rate sometimes takes a quick dip, perhaps due to extra holiday reading or from the many Kindles that Amazon sells for the holidays. If it does dip in January, note that it usually picks back up fairl -

ESSENTIAL CALCULUS SKILLS You learn a lot during a calculus course.
How much of this is useful?
Of course, it depends on what you do after calculus.
For example, much of the material is needed in higher-level math courses.
But how about for physics, engineering, and other applications of calculus?
derivatives of polynomials and trig functions are absolutely essential. You need to practice these until you’re fluent. for integration, sometimes -

Blog postCHECKING YOUR ANSWERS: Many math books post the answers to selected questions in the back of the book. Most of my workbooks include the answers to every question in the back of the book.
A few students get a different form of the same answer, and mistakenly believe that the answer in the back of the book is wrong, when it’s really correct.
One common example occurs when the student gets a squareroot in the denominator, like:
The above answer isn’t in standard form. Mo -

ESSENTIAL FRACTION SKILLS Not everyone loves fractions, but fraction skills are important for a number of reasons.
It helps to be fluent with fraction skills when you take algebra, trigonometry, and calculus courses. When you solve for an unknown in algebra, the answer doesn’t always turn out to be a whole number. One reason that cross multiplication is difficult for many students is that the problems inherently involve fractions. In calculus -

How do you multiply or divide powers of 10?
What are negative powers of 10?
What is 10 raised to the power of zero?
Compare positive and negative powers of 10. Note that the number of zeros is a little different with positive and negative powers of 10. See the chart below.

Blog postBlock Sliding Down an Inclined Plane Consider the block sliding down an inclined plane (with friction) illustrated below.
When we apply Newton’s second law to the box, we set the sum of the x-components of the forces equal to max and the sum of the y-components equal to may.
One of the forces is weight, which equals mg (mass times gravitational acceleration).
The x-component of mg has a sine function, whereas the y-component of mg has a cosine function:
(mg)x = mg -

Blog postUSING ALGEBRA IN ARITHMETIC It’s interesting that algebra can be useful in arithmetic.
Since arithmetic is a prerequsite to learning algebra, most algebra courses don’t focus on how to apply algebra to do arithmetic.
However, you can apply your algebra skills to arithmetic problems.
Following is an example.
Suppose that you would like to multiply 58 times 58, but don’t have a calculator (or cell phone) handy.
One way to do this, which is often taught i -

Blog postHOW TO FIND THE SLOPE OF A STRAIGHT LINE Slope is a measure that indicates how steep or shallow a straight line is:
A line with greater slope is steeper. A line with less slope is shallower. A horizontal line has zero slope. Slope can be positive or negative:
A line with positive slope slants upward. A line with negative slope slants downward. A line with zero slope is horizontal. The slope of a straight line equals rise over run.
The rise between two points is vertical. -
Blog postTRIGONOMETRY MEMORY TIP There is a simple way to remember the sine, cosine, and tangent of special trigonometry angles.
The special trig angles are 0º, 30º, 45º, 60º, and 90º. What makes these angles special? The 30º-60º-90º triangle is one-half of an equilateral triangle, while the 45º-45º-90º triangle is one-half of a square. In both cases, the trig functions (sine, cosine, and tangent) can be expressed as simple ratios.
