Eliminate 't'
November 7th 2010, 12:15 PM #1
The term "hyperbolic" coems from the fact that if we define the Cartesian coordinates of a point to be $x=\cosh t$ and $y=\sinh t$, where $t$ is so-called parametric variable, then elimination of
$t$ leads to the equation of $x^2-y^2=1$, the equation of an hyperbola.... | {"url":"http://mathhelpforum.com/calculus/162456-eliminate-t.html","timestamp":"2014-04-19T07:14:19Z","content_type":null,"content_length":"50356","record_id":"<urn:uuid:84417866-2ea3-4e7a-8baa-0f7af1f99883>","cc-path":"CC-MAIN-2014-15/segments/1398223207046.13/warc/CC-MAIN-20140423032007-00141-ip-10-147-4-33.ec2.inter... |
