Question

I need some help please? I'll attach the problem

Answer 1

only 3.

Answer 2

So for the first one, solve the "inside" first, what is the tan of pi/4?

Answer 3

1. right?

Answer 4

Now for the inverse cos of 1. You are trying to figure out what angle.
So cosx=1

Answer 5

wait, it's 0. that makes sense lol

Answer 6

i blanked when i came to the question

Answer 7

can you help with the other 2?

Answer 8

I can tell you the next one looks like a tangent graph

Answer 9

I am not sure if anything would be "added" since tan of 6pi would be 0

Answer 10

so the equation is y= tan6? idk

Answer 11

not with the 6 i just meant that I "plugged in" the value of 6pi

Answer 12

But they add some value to move it to the right

Answer 13

alright, so just y= tan?
any clue for the third one?

Answer 14

Nope @jim_thompson5910

Answer 15

I'm not sure about the third one either. It looks like another tangent function though.
