1. The problem statement, all variables and given/known data Hi, i don't really know how I should go about this question. please help me. Question: Integrate the following equation: I = (integration sign from 0 to 2 sqrt3) (x^3)/(16-x^2)^(1/2) 2. Relevant equations 3. The attempt at a solution I tried to assign u and dv initially like this: u = (16-x^2)^(1/2) du = -(16-x^2)^(-1/2) dx dv = x^3 dx v = (1/4)(x^4) so uv - (INT)vdu = (1/4)(16-x^2)(x^4) + (1/4)(INT)(x^4)/(16-x^4)^(1/2) dx but it gets more complicated because of x^4, if x^3 in the integration then i could have assigned it as I and then solve it easily, but i think i made a huge mistake somewhere to get it to be like this.
