A square root is the same as an exponential degree of 1/2, so a square root function can be integrated using the same formula for polynomials. A u-substitution for the expression under the square root symbol is a common additional step. Find the integral of square root functions by rewriting the square root as u^(1/2) and then finding the anti-derivative using the polynomial anti-derivative formula from calculus.
