Homework Statement
a) Eleminate the parameter to find a Cartesian equation of the curve.
b) Sketch the curve and indicate with an arrow the direction in which the curve is traced as the parameter increases.
Homework Equations
x = 2cosh(t) y = 5sinh(t)
cosh^2(x) - sinh^2(x) = 1
The Attempt at a Solution
cosh(t) = x/2 sinh(t) = y/5
(x^(2)/4) - (y^(2)/25) = 1
y = +/- sqrt(25/4(x^2) - 25)
This is the best guess I have here, and the graphs look similar... I just really don't know what to do from here (or even if I'm going about it the right way). Any help would be appreciated.
