$($d$)$ Write a Matlab script that does the following:

For $-10$pi $<=$ theta $<=10$pi create a vector @ with $100$ elements.

Use a for loop to loop over each element of $6$ to create the elements of a vector y such that y $=$ sin$($theta$)*$ cos$($theta$)$ Using an if statement, create a second vector z$,$ so that an element of z has a value of $10$ if the corresponding element of y is positive. Otherwise an element of z is given a value of $5.$

Plot & versus y and @ versus z on the same graph. Include the label $"8"$ on the x$-$axis.
