Question

Hey, can someone please explain how to do this

Find the Sin, Cos, and Tan of the following angle:
-45 degrees

(i need an explanation not just an answer because i have a test tomorrow)

Answer 1

i am learning this right now and i think that all you would have to do is the number into the "equation" with the negative sin, cos, tan, close the parenthesis then press enter or =

Explanation:

Sin^-1(-45)=

cos^-1(-45)=

tan^-1(-45)=
