Answer:
Step-by-step explanation:
LHS= Tan theta - Cot theta
Sin theta/cos theta - cos theta/sin theta
Sin^2 theta - Cos^2 theta/ Cos theta * Sin theta
Sin^2 theta - (1- Sin^2 theta)/Cos theta * sin theta
Sin^2 theta - 1 + sin^2 theta/ cos theta * sin theta
2 Sin^2 theta - 1/Cos theta * Sin theta
Thus LHS = RHS
