The shaping always moves forward. even if the progress breaks down you have to take a step back before moving forward again but there is no such thing as backward shaping

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 

You should ease the seat belt back slightly and slowly
