hi,

I need help on sketching the curve for x=2sect, y= 3tant, -(pi)/2< t <(pi)/2

thanks

You can either plug in some values for t to find some points and plot the curve or you could use (secx)^2-(tanx)^2=1 to find the cartesian equation which might help you to visualise it more.

The curve is a hyperbola i think.

I would do it the y=mx+c way because you have a sec and tan:

x=2sect

x²=4sec²t

y=3tant

y²=9tan²t

tan²=sec²t-1

y²=9(sec²-1)

y²=9(x²/4 -1)

and work from there...

I only knwo how to do it on the casio ones... but if you have a graph option on the main menu and go under it, if there is any TYPE button, whatever your calculator parametrics (Parm) will be there if anywhere.
