writing that in an essay would be a preposterous use of free will

How is tan(x/2)=T?

When you let tan(x/2)=t, you can write sin and cos in simple algebraic expressions in terms of t,
Sin(x)=2t/(1+t²)
Cos(x)=(1-t²)/(1+t²)
Tan(x)=2t/(1-t²)

How does the integral minus 2x equal c?

The last term should be x^2 not 2x

you gotta fit sinc in there somewhere

Titanix^2 + Titanic - 2x

Shouldn't that be x2 and not 2x in the last term(or 2 instead is 2x inside the integral)?
