### GRE Math Subject Test Sample Question #1

What is the length of the parametric curve: f(t) = (x,y) = (cos(t),sin(t)), for t in [0,Pi] ?

### GRE Math Subject Test Sample Question #1

What is the length of the parametric curve: f(t) = (x,y) = (cos(t),sin(t)), for t in [0,Pi] ?

Update: Mike got the answer lightning-/mike-fast. Here's the output of parametric_plot() below:

Update 2: Per Mitesh's suggestion, I called parametric_plot() with keyword argument "aspect_ratio=1"; the image below looks more round with a 1:1 aspect ratio:
