Q$1$

Create a MATLAB script file to calculate the following expression:

$y=co{s}^2(\frac{3x}{5})+tan(\frac{x^{1\mathrm{.}7}}{11})$ where $x=2$

Q$2$

Create a MATLAB script file to plot the function

$y=5\sqrt[\phantom{2}]{t}-\frac{(t+2{)}^2}{0\mathrm{.}5(t+1)}+8$

over the interval $1t4.$ Put a title on the plot and properly label the axes. The variable $y$ represents temperature in degrees Fahrenheit, and the variable $t$ represents the time in seconds.

Q$3$

: Create a MATLAB script file to plot a Logarithmic Spiral on the $xy$ plane:

$x=$acos$e^b$;$,y=$asin$e^b$

over the interval $06$ where $a=\frac{}{4}$ and $b=0\mathrm{.}2.$ Put a title on the plot and label the axes.
