Return to Assignments Tangent line to graph

### Assignment 6

Calculate the equation of the tangent line at the point of the graph of the function:

### Solution

First we calculate the slope of the tangent line at the given point and we do this by differentiating the function:

In the point the slope is (always check whether such a point lies on the graph):

So we have to calculate the equation of the line through with slope . We find the line by using the following formula:

or:
