dxd∫abf(x)dx
For the Fundamental Theorem of Calculus (part 1), you want
a to be x, and b to be a number
a to be a number, and b to be x
a and b to both be numbers
a and b to both be x
dxd∫abf(x)dx
For the Fundamental Theorem of Calculus (part 1), if b is 2x, you will have to use

If F is the antiderivative of f, then ∫abf(x)dx is
f(a) - f(b)
f(b) - f(a)
F(a) - F(b)
F(b) - F(a)
