"I bet you can't tell me something that will make me both happy and sad at the same time," a husband says to his wife. She thinks about it for a moment and then responds, "Your pe n is is bigger than your brother's."

To solve this integral, what you can do is split it up as follows: (1) ∫40(x2−4)dx=∫40(x2)dx−∫40(4)dx. to integrate  4  as an  indefinite integral, a good rule of thumb is  by  an equation below  for  polynomials; . (2) ∫xa=xa+1a+1+c , where a is any number. c denotes some constant that is crucial when doing
