Vertify the identities, clearly show each step (vertify one side that they are equal to each other)

sec^2+csc^2=sec^2+csc^2

• Pre Cal -

The left-hand side is already identical to the right-hand side.

If the question was
sec^2+csc^2=sec^2 csc^2
then you only have to add the left-hand side together:
sec^2+csc^2
=(sin^2+cos^2)/(cos^2 sin^2)
=1/(cos^2 sin^2)
=sec^2 csc^2

Hello all, In our math class, we are practicing the trigonometric identities (i.e., sin^2(x)+cos^2(x)=1 or cot(x)=cos(x)/sin(x). Now, we are working on proofs that two sides of an equation are equal (for example, sin(x)*csc(x)=1; sin(x)csc(x)=sin(x)/sin(x)=1; …
