Trust me you don't want to answer this

Manual pipetting creates a musculoskeletal load on the neck, shoulders, and upper limbs and the type of injuries that this can lead to is called repetitive stress injuries.

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
