The Trigonometry and Pre-Calculus Tutor is the easiest way to improve your grades in Trig and Pre-Calculus! How does a baby learn to speak? By being immersed in everyday conversation. What is the best way to learn Trig and Pre-Calculus? By being immersed in it! During this course the instructor will work out hundreds of examples with each step fully narrated so no one gets lost! Most other DVDs on Trig and Pre-Calculus are 2 hours in length. This DVD set is over double the running time and costs much less! See why thousands have discovered that the easiest way to learn Trig and Pre-Calculus is to learn by examples!
From the Contributor
I have tutored many, many people in Math through Calculus, and I have found that if you start off with the basics and take things one step at a time - anyone can learn complex Math topics. This 2-DVD set contains 5 hours of fully worked example problems in Trig and Pre-Calculus.
After viewing this DVD course in Trigonometry and Pre-Calculus you'll discover that the material isn't hard at all if it is presented in a clear manner. No knowledge is assumed on the part of the student. Each example builds in complexity so before you know it you'll be working the 'tough' problems with ease!

I want to say a couple things about the videos overall, and then about this specific one. The videos are meant to be a supplement to a textbook and class. In none of the DVDs I have purchased so far has Jason covered every topic that was discussed in class. He focuses on the foundation topics from which others build. If you think you can just study the material on the DVDs then show up for quiz and test days and get an A in the class, you are greatly mistaken. The best you could hope for with that plan is probably a C. If you know the core/fundamental material well, which this will give you, you will be well prepared to tackle the more difficult concepts that will be presented in class.
As for this DVD in particular, it focuses almost exclusively on the trigonometry, and less so on the algebra. The way most college level pre-calculus classes are set up, including the one I am in, is you do a review of algebra then get into the trig. The only algebra presented in this DVD are exponential and logarithmic functions and complex numbers. I am sure that Jason did not want to be too duplicative with the material on his algebra DVDs, which is probably why he focused more on the trigonometry. I know one of the reviews for this DVD said something along the lines of "this does not cover all the material in a pre-calc class." That is most likely the reason why.
As I said in a review of one of the algebra DVDs, this is a no frills presentation. It is a guy in front of a white board doing multiple problems. It is not exciting or flashy. Whether you are going to find this useful depends on your learning style. If you can learn just watching a lecture style presentation, but one in which you cannot interact and ask questions of the instructor, these will be very useful. If you are someone who learns more by asking questions and interacting and find the idea of watching someone do math problems on TV mind numbing, then you are not going to find this useful and would probably benefit more from a tutor.
Now that I have finished my class I wanted to provide an update to this review. As I said in the comment to one of the other reviews for this product, and somewhat above, there was no perfect way for Jason to make this DVD. That has about as much to do with how many pre-calculus classes are structured as it is anything else. If you use this along with his advanced algebra tutor set, you will get about 90% of all the material covered in most college level pre-calc classes. You really have to look at those as one long DVD set. Most of what is in the trig/pre-calc DVD will not be covered in college algebra, but a lot of what is covered in the advanced algebra DVD will be at least touched on in pre-calc. That is not even to say everything in the trig/pre-calc DVD will be covered in every pre-calc class either. In my class for example we did not spend any time on imaginary/complex numbers.
As for what is included in the trigonometry portion, Jason does go through all the fundamental concepts you need to learn to do well. It is the stuff that if you do not understand it, you will be hopelessly lost when you get to the more advanced material. The one change I would have made to the DVD is I would have included more of the trig identities like the double angle and half angle identities, and included a section on conics. That said, the information he does give about manipulating the trig identities are the most used, and the most important ones to memorize. Finally, you have to keep in mind this is a five hour DVD set. There is no way to distill 10-15 weeks worth of information into five hours. It is imperative to look at this as a supplemental tool, not a replacement for going to class and doing homework. Anyone who looks at this as a replacement for those things will fail miserably and have no one to blame but themselves.
Jason has released a second part to this set that fills in many of the gaps in what he did not cover here. The Trigonometry & Pre-Calculus Tutor - Volume 2 - 6 Hour Course! It covers more of the trig identities like the half angle and double angle, even-odd, etc. There is also a section on covering trig equations and a lot of material on the law of sines and cosines. As I originally said in my review it covers the things that should have been in the original release with the exponential, logarithm and imaginary number stuff taken out. Personally I think those subjects would have been better served to be on one of his algebra DVDs. It had to be a judgment call though, and due to the fact that there is not a lot of uniformity between how and when trig is presented in a school's curriculum there was no perfect way to do it. If you go to a school where trig is presented as a single class than this set will be better, especially when added with volume 2. If however your school does a review of algebra then goes into trig then this will seem very lacking. But, given that Jason had already put out two advanced algebra DVDs, it was not practical to put all that material on this one as well. Nor should he have to apologize for referring people back to the other set if they need to brush up on algebra concepts. In all, if you have this set, volume 2 of this set, and his algebra DVDs, the only thing you will be missing is the material on conics that you will hit at some point. Those are really about using algebra to study circles, ellipses, parabolas and hyperbolas. They are not something you will use trig for, so if your algebra skills are good you will be OK. Some pre calc classes also start introducing you to the concepts of vectors (to get you ready for physics), but Jason does cover those extensively in his physics tutor DVD set The Ultimate Physics Tutor - 11 Hour Course! - 2 DVD Set! - Learn By Examples!.
The instructor is great pointing out every step in the solution. I wish I had this crutch when I took Trig. A great buy and sure to work specially if you, like myself, do not have a natural ability in mathematics.
One major caveat. Significant aspects of pre-calc are not mentioned in this set. So don't think that just by reviewing this set you will be ready for calculus. Not by a long shot.
I am looking forward to getting into the "Calculus Tutor" set by the same instructor.
