It is because the partial fractions are simply another way of expressing the same algebraic fraction.

Tapered integration is partial integration and not full vertical integration. Therefore tapered integration is when a firm both makes and buys similar products or services.

A single number, such as 4228, cannot have partial fractions.

The exact method used to integrate the partial fractions of a given fraction cannot be predicted without knowing the exact form of the partial fraction. I list below some examples: If the partial fractions are of the form 1/(ax+b) where a and b are constants and x is the dummy variable, the integral will be (1/a) ln(|(ax+b)|)+C, where C is the integration constant. You may solve denominators of second degree by using method of completion of squares.

Partial vertical integration is the action in which a firm aquires control in either an upstream supplier or a downstream buyer with a share ratio of less than 100 % in the integrated firm.
