What is an integral? • An integral is the generalized summation of a function between two boundaries definitely or indefinitely. • In Physics, often the area under the curve is known as the integral • In math, integral can find the summation of the curve
Bruce’s Law for Integral • Do exactly the opposite of what you do to find a derivative…I mean it. • Example: take f(x) = axn To find the intregal of f(x): ∫f(x) = axn+1 + c n+1 The “c” is any constant, it’s always there if it’s an indefinite (no boundaries) integral

Cases • Fundamental Theorem of Calculus • Basically, given a function, to find the value between two boundary. Take the integral of the function and subtract the value of the two boundaries. • Ex: ∫ab f(x) = F(b) – F(a)
