Question

verify the identity
1 + (sec^2)x *(sin^2)x = (sec^2)x

Answer 1

For these types of problems it helps to write it all in terms of sin and cos. so sec x = 1/cos x, csc x = 1/ sinx, and cot x = cos x/sin x.

Try this and see what you see

Answer 2

\[1 + {1 \over \cos^2x} \times \sin^2x = {1 \over \cos^2x}\]

Answer 3

i still am confused...this isnt my strongest subject

Answer 4

\[1+\tan^2x=\sec^2x\]QED
