Question

Simplify: (Sec[x]^2 + Csc[x]^2) - (Tan[x]^2 + Cot[x]^2) into a constant or basic trig function. The answer is 2, but I don't know how to get there.

Answer 1

sec^2x + cosec^2x -tan^2 x + Cot^2x

Answer 2

Hint :

1+ tan^2x = Sec^2x

1+cot^2x = cosec^2 x

Answer 3

Hope u can Solve it nw..:)
