Question

If sin theta minus cos theta is equals to zero then find the value of theta and sin theta

Answer 1

Basically sinA = cosA
Or tanA= 1 (sinA / cosA)
So, A=45
So sinA. = 1/rt2

Answer 2

Answer:

sin@ - cos@ = 0

sin@ = cos@

values of sin and cos is equal when theta(@) is 45°

so theta = 45

and values of sin@ and cos@ is 1/√2.
