q-25) given - sin theta =cos theta so only if theta = 45 this situation is possible
theta =45
tan^2 theta is 1 and
2tans^2 theta= 2
now sin 45 = 1/ root 2
sin ^2 45 = 1/2
so
2- 1/2 -1 = 1- 1/2 = 1/2
theta =45
tan^2 theta is 1 and
2tans^2 theta= 2
now sin 45 = 1/ root 2
sin ^2 45 = 1/2
so
2- 1/2 -1 = 1- 1/2 = 1/2
