Some Examples:
Example: solve to find
Then plot to find that it is indeed the right side of a parabola Ð due to
restrictions on the time ()!!!! (use window tstep=.01)
To go in the other direction, you can usually simply substitute either
or , but this won't help you graph the entire function!
Example: Try plotting in parametric mode.
If just , we haven't gained anything Ð it is still just the
top half of the ellipse!
try using
Example: Which trig sub should we use?
When we plot these, what values should we use?
Other Examples to (try to) convert:
