Question

Prove that 1 + sin theta minus cos theta by 1 + sin theta + cos theta whole square equals to 1 minus cos theta 1 + cos theta

Answer 1

Answer:

u should do this problem by nz(nuthans zero)method.

Step-by-step explanation:

take lhs,

1+sin theta minus cos theta by 1+sin theta whole square.

take rhs,

1minus cos theta 1+cos theta.

multiply zero on both sides,

u will get 0=0,

hence lhs =rhs,

proved.
