2. Bowditch curve
The Bowditch curve is defined by the parametric equations
x = sin(t/2), y = sin(t)
It is a closed curve meaning it begins to repeat itself as t gets larger and larger.
%3D
a. Starting with t= 0, determine the first t-value greater than 0 such that the curve begins to repeat
itself.
b. Find an equation for the tangent line when t= 0.
c. From the above plot, it is clear there are four points on this curve where the curve has
ntal
tangents. Find t-values for these four points and then give the (x, y) coordinates for these points.
d. There are two points on this curve where the curve has vertical tangents. Find t-values for these two
points and then give the (x, y) coordinates for these points.
e. Calculate the length of this curve. (Use technology to compute any integrals.)
