Question

how would I find the exact value of TAN(-765degrees)?

Answer 1

@mathmath333 you know anything about trig?

Answer 2

reduce the angle first

Answer 3

add 360

Answer 4

two times i think

Answer 5

hint:
tan(360)=0
tan(720)=0
now write 765 as 720+45

Answer 6

I don't get it our teacher was absent today and never gave us a powerpoint to look over

Answer 7

I'll just ask the teacher tomorrow

Answer 8

u need to add 360 here
\(\large\tt \begin{align} \color{black}{
tan(-765)\\
=tan(360-765)\\
=tan(-405)\\
=tan(360-405)\\
=tan(-45)\\
=-1\\
}\end{align}\)

Answer 9

formual is \(tan(2\pi+\theta)=tan\theta\)
