Question

If sin theta = cos theta , find the value of theta , find the value of n

Answer 1

hello dear only one condition for sin theta and cos theta are equal when the value of theta is 45 degree in first quadrant
, hence the theta =45 degree

I hope its help you dear :-)

Answer 2

sin θ = cos θ

sin θ/cos θ = 1

tan θ = 1

tan 45° = tan θ

θ = 45°
