[SOLVED] why cant I remember how to integraTE

You want help to Integrate it or just saying why can't you remember the table formula and you want someone to give it to you?

$$\int x^2\ln xdx$$

Integrate by Parts: $$I=uv-\int vdu$$

$$u=\ln x$$
$$du=\frac{dx}{x}$$

$$dV=x^2dx$$
$$V=\frac 1 3 x^3$$

Are you answering my question, or just asking me to restate the original.

Smoking funny cigarets? Drinking too much? Misplaced capitals syndrome?
