Document Summary

1. let the more complicated one (and the one that when differentiated, leads to the qn*dx) be u: differentiate that u to get du/dx, substitute 2 into equation to find the equation in u, differentiate normally. 2 methods to integrate for definite integral: make the indefinite integral into a definite one. Substitute the boundaries at the final result. Integrate the equation as if it does not have boundaries (do not change the boundaries to u, leave it as it is) Do it as if = cosx(sinx + 1) 3. When you substitute the boundaries back, you can ignore the c" (it"s a constant that will cancel off: rewrite the boundary in u, integrate with boundaries intact. In this case, we let u = g(x) Substitute a and b into g(x) to find the new boundary (in u) Substitute such that the equation is __ du (__ in u")
