Use these coordinates to find the gradient of the line. Image caption ... Architects have to understand gradient to work out the slope of a roof. There are rules and regulations for how steep ...

The point slope form is particularly useful when you have these two pieces of information and need to find the equation of the line ... obtain solutions and graph the equations.

{3}\text{.}\) One of graphs in Figure 4.3.1 is the graph of \(r=4\cos(3\theta)\text{.}\) Indicate which one by circling it. Find the slope of the tangent line to the curve where \(\ds \theta = ...
