1. The problem statement, all variables and given/known data 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. 2. Relevant equations x = 2cosh(t) y = 5sinh(t) cosh^2(x) - sinh^2(x) = 1 3. 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.
