These are some of the most frequently encountered rules for differentiation and integration.

The function to be integrated becomes simpler when we replace some portion of the function with u.

If both m and n are odd natural numbers then put either sin x = t or cos x = t. Z ax dx= ax ln(a) + c with base e, this becomes: For the following, let u and v be functions of x, let n be an integer, and let a, c, and c be constants. If n is an odd natural number then put sin x = t.
