Units, Functions and Plots

Background:

Matlab has built$-$in sine and cosine functions. It takes arguments in radian unit.

$x$ radians $=x**(\frac{180}{})$ degrees $($ This is the conversion from degrees to radians$)$

$$ radians $=**(\frac{180}{})$ degrees $=180$ degrees

$y=sin(x)$ : In this equation $\text{'}x\text{'}$ represents the input value of the sine function and $\text{'}y\text{'}$ represents the output value, sine of $x.$

xlabel and ylabel functions label the axes. $($Example: xlabel $(\text{'}$Radians$\text{'})$;

title functions add a title label to your figure. $($Example: title $(\text{'}$LASTNAME NAME'$)$; $).$

legend function draws a legend on the plot. $($Example: legend$(\text{'}$Sin$\text{'},$ 'COS'$)$; $)$

Problem Statement:

Sine and cosine are two most common trigonometric functions. In this problem, we will investigate the behavior of these two functions by plotting them with two different colors. assigned.
