Bought these for someone going to college.

Had to get all three of your books! They are so helpful. Real time savers in learning. Thank you! You know what you are doing. There is still a lot to learn but this makes it a lot easier getting going in the right way and avoiding many of the common mistakes. Thanks for paving the way.

Forgettable ways to memorize trig formulas

This is a worthless book. The techniques provided to memorize formulas or to generate values of trig functions for special angles (30 degrees, 45 degrees, 60 degrees, etc) are harder to memorize than the formulas or values themselves. The one easy thing to memorize Sarswat gives is SOHCATOA for the basic trig functions of a right triangle, but everyone knows this already. With more complex trig identities, like the sum and difference formulas, the memorization techniques Sarswat supplies are complicated derivations. But when using the identities, one wants an easy way to memorize them along the lines of mnemonic like SOHCATOA. One doesn't have time to derive them from scratch. You'd be better off thinking up ways to memorize them yourself than purchasing this book.

Really loved the book and its concept

It is a unique book which allows students to learn unusual methods and tricks to learn various formulas of Mathematics (Trigonometry in general). I have read the part - 1 of the book as well which deals with the formulas of Calculus. Really loved the book and its concept.

Buyer Beware! This is NOT compatible with Kindle Paper White. Just another useless Ripoff.

NOT compatible with Kindle Paper White. Bought both volumes and can't download them or use them. Ripoff.This doesn't deserve one star.
