<p>Last year, when my pre-calc honors class was covering trig identities and proofs, we all thought that they were easy except for memorizing the identities. However, the average on the chapter test was a 70%. LOL</p>
<p>They help a lot with differentiating and integrating lol. Many problems require trig substitutions that wouldn’t be possible to solve without knowledge of trig identities. Besides, trig functions are much more interesting than the other basic functions.</p>
<p>Lol yea, I’m in precalc. Finally finished the homework, I will be very excited if I got one right lol. I find it funny that you describe them as “interesting.” :)</p>
