Q$1.$ Use MATLAB to evaluate the following

Remember:

Using parentheses appropriately will lead to the correct calculatons.

Use the same variable names as given in the problem statement.

using square brackets $[]$ in Algebra is OK but in MATLAB they are dedicated to arrays and should not be used in calculations. $($Only parentheses should be used for mathematical operations in MATLAB, and you can use as many nested parentheses as you need$)$

Hint: MATLAB assumes angles are entered in radians when you use trig ratios $($sin$,$ cos$,$ tan$).$ You can either use the versions of the trig ratios that accept angles in degrees $($sind$,$ cosd$,$ tand$),$ or convert the angle to radians using deg$2$rad$($angle$)$ then use the regular trig ratios.
