Yeah, you can cry underwater but you just can't see the tears since you're already in water. just because you're crying doesn't mean you have to feel the wetness of your tears. s ya

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 

Ithink the answer is bhope this !
