MATLAB contains a wide variety of built$-$in functions, such as abs $($absolute value$)$ and eig $($eigenvalues$).$

$a=sin(-5)$

$a=0\mathrm{.}9589$

Pass inputs to functions by using parentheses, similar to function notation in math.

TASK

Calculate the sine of $x$ by using the sin function. Assign the result to a variable named $y.$
