Question

1/1+cos^2 thetha + 1/1+sin^2 theta + 1/1+sec^2 theta + 1/1+cosec^2 theta = 2

Answer 1

Answer:

Step-by-step explanation:

=1/1+cos^2 thetha + 1/1+sin^2 thetha + 1/1+sec^2 thetha + 1/1+cosec^2 thetha

=1/1+cos^2 thetha + 1/1+sin^2 thetha + 1/1+1/cos^2 thetha + 1/1+1/sin^2 thetha

=1/1+cos^2 thetha + cos^2 thetha/1+cos^2 thetha + 1/1+sin^2 thetha + sin^2 thetha/1+sin^2 thetha

=1+cos^2 thetha/1+cos^2 thetha + 1+sin^2 thetha/1+sin^2 thetha

=1+1

=2
