### ⭐ Forgettable ways to memorize trig formulas
*by M***H on March 13, 2018*

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.
