Question

for sin, cos, tan, csc, sec, and cot functions, how do you find the angles?

Answer 1

i know you type in the calculator inverse sin..etc but like how do you know which quadrants they are in

Answer 2

the inverse functions

\[\sin^{-1} or \space \cos^{-1} or \tan^{-1} \]

and so on

Answer 3

i know that

Answer 4

but how do you know which quadrant

Answer 5

once you find that reference angle

Answer 6

Ah, ok i got it

Answer 7

Just remember that the cos is like x and the sin is like y. That gives you the sign of all the functions in all the quadrants.

Answer 8

hmmm still sorta confused. can you give me an example mertsj?

Answer 9

you have to check the value of the function

in the first quad. all functions are positive
in the second quad. sine is the only positive the rest are negative
in the third quad. tan is the only positive the rest are negative
in the fourth quad. cosine is the only positive the rest are negative

so when you find the angle , you can determine in which quad it is.

Answer 10

ok so like if i have sin x = 1/2
