Use the attached figure to guide yourself through the explanation. In the figure:
.
We know that:
Also remmeber that the area of a triangle is:
The hegiht is shown in the figure in red, the base is just the b side.
Using the angle C the area of the triangle is:
Now taking the derivative of the area 2A with respect to t we have:
Replacing with the right values:
yields:
