.........you can't solve an Identity.

For example, "a man is a male"..........nothing to figure out about that statement.

no, you have to prove that they equal

Sorry, they are equal.

easier way factor our sec^2 x sec^2x (1+ csc^2x /sec^2x) =sec^2x (1+ cot^2x) = sec^2x * csc^2 x

@hartnn That approach can only be used when you already know that they are equal. You have to isolate each part when verifying.

@primeralph i cant read your work

@Summersnow8 Just simplify both.

we all already know they are equal, we are just verifying, we can do, what i have done....we must know the identities
hartnn
  • hartnn
there are 4 identities i have used, csx x = 1/sin x sec x = 1/cos x cos x/sin x = cot x and 1+cot^2x = csc^2x rest is just algebra work
