Question

14. sec²A + cosec²A = sec ²A cosec²
prove that​

Answer 1

Answer:

:-LHS= sec²+cosec²

=1/cos²+1/sin²

=sin²+cos²/sin².cos²

LHS=1/cos².sin² (SIN²+ COS²= 1)

:-RHS=sec².cosec²

=1/cos². 1/sin²

RHS=1/cos².sin²

THEREFORE, LHS=RHS

Answer 2

Answer is attached above.... Hope this helps you
