I am trying to learn calculus as part of a catch up course for a degree. Finding the derivative of a function makes sense to me but finding the integral of a function: I just can't get my head around.
This is the question: Find the indefinite integral and evaluate the definite integral from $-1$ to $+1$.
The function is written like this: $$f(x) = 2x^2 - 3x + 5$$ Could someone break down the method for integration of the above into small steps that I can wrap my head around? Thanks!
