Question

For what value of 0 , sin 0 = cos 0 (a) 0⁰ (b) 30⁰ (c) 45⁰ (d)60⁰​

Answer 1

Step-by-step explanation:

GIVEN...

Sin = Cos 0

As we know that the formulae, Sin

(90 - theta) = cos theta

on applying the formulae in above

equation we get,

sin theta = sin(90 - theta)

on comparing both the equations,theta = 90 - theta

2theta = 90

theta = 45
