Question

tan(sin^-1(-1))=?

Answer 1

first start from sin^-1(-1)

Answer 2

do you know what is it ?

Answer 3

no

Answer 4

i dont remember how to solve for inverse functions

Answer 5

well just think of a value between -pi/2 and pi/2 for sine function that gives -1

Answer 6

honestly , i am so confuse. i havent done these since first semester

Answer 7

use a unit circle

cos is horizontal component
sine is vertical component
tan is ratio sin/cos

First find the angle such that sin(angle) = -1
then compute tan(angle)

Answer 8

answer is -1/0 which approaches -infinity
