Question

if cos theta -sin theta =0 and 0 and 0°<theta <90° find the value of theta​

Answer 1

Step-by-step explanation:

cos theta - sin theta=0

cos theta = sin theta

sin theta/cos theta =1

tan theta =1

tan theta = tan 45°

theta =45°

Answer 2

Step-by-step explanation:

here,

cos theta -sin theta=0

cos theta =sin theta

it is only possible for theta =45°

cos45°=sin45°

1/root2 = 1/root2

theta =45°
