I only need the Excel part

Solve in Excel and MatLab. Each solution is worth $10$ points for a total of $20$ points this question.

A graph is described by the following parametric equations:

$x=2sin(t+cos(at))$

$y=2cos(t+sin(at))$

Plot this geometric figure for a value of $a=100$ in Excel. You must choose enough values for $t$ so that the curves are smooth.

In Matlab plot $4$ equations on the same page investigating the following values of a: $20,50,100,200.$ Use looping to your advantage.

Make a tab called Parametric Eqns in the excel workbook.
