Can someone help me on this assigment?

Problem Statement An asteroid is a geometric figure as described in the following link: http://mathworld.wolfram.com/Astroid.html As described there, the parametric equations can be obtained as: 3 b cos t b cos (3 t) 4 b cos t a cos t 3 b sin -b sin (3 t) 4b sin t a sin t You are to write a Matlab function definition which, for a given values a and b will ploft the figure over the parametric interval-2 t 2. A related curve is the catacaustic (see: http://mathworld.wolfram.com/AstroidCatacaustic.html) Also plot the catacaustic of the asteroid over the same range for the case a=b=1. The parametric equations can be defined as
