As per the formula we have to consider dvdx as one function and u as another function. Integration is the operation of calculating the area between the curve of a function and the x-axis. This yields the formula for integration by parts.
X 2 1 d x sin.
We already found the value dudx 1. F xg xdx f xg xdx f xg xdxdx Which can be further written as integral of the product of any two functions First function Integral of the second function Integral of differentiation of the first function Integral of the second function. In other words this is a special integration method that is used to multiply two functions together. The cosecan integral can be deduced if you know some derivation formulas then we will see how to get to the result of -log leftcot ucsc u right with the derivative formulasLet us begin.
