Explore by rotating the hypotenuse about the circle's center. By calculating the ratio adjacent/hypotenuse for different values ofθ, we can construct the graph ofcosθ. Change the value of r with the slider and notice that this ratio is not affected. ...

B) {eq}r = 2 + 3 \cos( \theta) {/eq}. Graphs: The Mathapp will be used to sketch the graph. Since the graphs are very informative and hence it can be used to find the area of the bounded region and find the critical points and the inflection points. ...
