(use window tstep=.01)
To go in the other direction, you can usually simply substitute either
or
, but this won't help you

Example:
Try plotting in parametric mode.
If just , we haven't gained anything Ð it is

try using
Example: Which
trig sub should we use?
When we plot these, what values should
we use?
Other Examples to (try to) convert:
