If we want to evaluate the integral ) * I= 1= x+29 √2+25 we use the trigonometric substitution x = becomes, in terms of 0, dx, I= de The antiderivative in terms of 9 is (do not forget the absolute value) I= and dx= Finally, when we substitute back to the variable x, the antiderivative becomes Use C for the constant of integration. MY NOTES de and therefore the integral +C
