What do we need to know for Trig?

[Cofo]

I am sure we have to know this stuff...
sin, cos, tan, csc, sec, cot
negative identies, double angle identities, unit circle
conversion between degrees and radians

But, is there anything else we need to know? What about what a sin graph looks like...or...know what a graph of a function looks like?

I read a breakdown once about someone being asked to manipulate sin/cos graphs in their QR section.

i accidentally drew them on my scrap paper, but mislabeled them. I was pretty upset with myself, a simple mistake cost me there. math was my favorite section too 🙁

just wanted to vent, good luck!

You also need to know the inverse trig functions ( arcsin arccos arctan )
