Prove:


cot(x) + 1 / cot(x) -1 = 1 + tan(x) / 1- tan(x)


tan(x) / 1 + cos(x) + sin(x) / 1 - cos(x) = cot(x) + sec(x)csc(x)



sin(x) + cos(x) = sin(x) / 1 - cot(x) + cos(x) / 1 - tan(x)

What do YOU think ?
While we're happy to HELP we wont do all the work for you.
Show us what you have done and where you are having problems..

You need to learn to use parentheses - the equations as you have written them make absolutely no sense. To get started I suggest you convert the tangent, cotangent, secant and cosecant functions into their sine and cosine equivalents, then look for ways to siimplify fractions and apply some of the more common identities, such as sin^2x + cos^2x = 1.
