Question

sinx = 3/5 , x lies in second quadrant find all the thethas

Answer 1

Step-by-step explanation:

sin x = 3/5

sin^2 x + cos^2 x = 1

(3/5)^2 + cos^2 x = 1

cos^2 x = 1 - 9/25

cos^2 x = 16/25

cos x = + or - 4/5

But x lies in the second quadrant, so

cos x = -4/5

cosec x = 1 / sin x

cosec x = 5/3

sec x = - 5/4

tan x = -3/4. and cot x =-4/3

hope it helps u friend
