Question

if sin teta is 3/5 then the value of [1- cos square teta ] is

Answer 1

Answer:

9/25

Step-by-step explanation:

sin theta = 3/5

we know,(1- cos²theta) = sin² theta

so, the value of (1 - cos²theta) will be...

(3/5)²= 9/25

hope it helps..

Answer 2

Answer:

9/25

Step-by-step explanation:

Given:

sin θ=3/5

then,

cos θ=4/5 [pythagorean triplet]

therefore,

1-cos²θ=1-[4/5]²

=1 - 16/25

=25-16/25

=9/25
