Question

If sin Θ =5/6 , what are the values of cos Θ and tan Θ

Answer 1

are you supposed to use inverse sine for this?

Answer 2

i dont think so

Answer 3

do you know how to solve it

Answer 4

yes, we know the identity sin^2 x + cos^x = 1
so solve that equation for cos^2 x and we get cos^2 x = 1 - sin^2x
then taking the square root of both sides
cos x = sqrt(1 - sin^2 x)
we know sin x = 5/6
so substitute that in and simplify
