i) The Fundamental Theorem of Calculus(part 2)
The Fundamental Theorem of Calculus: Suppose f is continuous on [a, b], then
∫abfxdx=Fb-F(a), where F is antiderivative of f, that is F'=f.
ii) Separate out the integration and then use antiderivative of each term
By separating the square root sign from the numerator and denominator and taking the inverse
By using the antiderivative,
Applying the Fundamental Theorem of Calculus,
