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:
![]()
