Thread: Parametric function involving trig

Hi all
I have this high school maths problem where i am given two equations which are parametric and am asked to find a cartesian equation from them. Normally i would be able to do this on my own, but i have never seen a question like this that involves two sin functions rather than a cos and sin

here are the equations

x=-4sin(Pi(t))/6) -(2pi)/3
and y=-3sin((Pi(t))/3) -pi

Any help would be greatly appreciated

Many thanks

thanks man you've been a huge help
