Composite Trig Functions (Nested Inverse Trig Functions)

Nested Trig Functions (Composite Functions)

Like Russian dolls, these problems have one trig function inside another, such as sin^-1(cos60). This is a type of problem that every trig teacher loves, so I've given them their own video. They're not too bad if you break it down and work from the inside out. I'll also show you a trick to spot whether they'll just cancel each other out, like in Arcsin[sin(60)].
