Answer:
Step-by-step explanation:
To show
=cos^2(45 + theta) + cos^2(45 - theta) / tan(60 + theta) tan(30 - theta) = 1
LHS =cos^2(45 + theta) + sin^2{90 - (45 -theta)} / tan(60 + theta) cot{90 - (30 - theta)}
=cos^2(45 + theta) + sin^2(90 - 45 + theta) / tan(60 + theta) cot(90 - 30 + theta)
=cos^2(45 + theta) + sin^2(45 + theta) / tan(60 + theta) cot(60 + theta)
= 1 / 1
LHS = 1 = RHS
