Question

helppp

Answer 1

tan x = sinx /cos x

tan x * cos x = sin x

- (sqrt 15)/ 4 * (sqrt15)/ 15 = - 15/60 = -1/4

Answer 2

-1/4 is the answer...use sinx=+-sqrt (1-cos^2x)....choose sign - because tan(x)=sin(x)/cos(x) is positive :D

Answer 3

how would i find the csc ,sec and cot?

Answer 4

csc x is 1/sin x. csc x = -4

sec x is 1/cos x. sec x = - 4 (sqrt15)

cot x = 1/ tan x = 15/ (sqrt 15)
