MATLAB

in this problem, in the calling script:

$$ Asks the user to enter an angle. $($ could be in degree or radian$)$

$$ And a letter: r for radian, or d for degree, $($with radian as the default$).$

$$ Then the script calls a function called my$\_$trig with the above angle and the

letter as input, calculates the sin$,$ cos and tan of the entered angle. The function

also pays attention to whether the angle is in degree or radian by using the right

function $($example: sin when the letter is r$,$ and sind when the letter is d$)$

$$ The output must be in form of a sentence similar to the following example:

$$You entered $45$ in degrees and the sine is $"$
