Write and compile a MATLAB $.$m file that satisfies the following requirements

The current in a series RLC circuit is given by:

$I=\frac{V}{R^2+(L+\frac{1}{C})}$

where $=2f.$ Calculate the current I for the circuit shown if the supply voltage $V=80$volts, $f=50Hz,L=400{10}^{-3}H,R=6,$ and $C=40{10}^{-6}F.$

$2.$ The acceleration of a spring is described by

$a=-A{}^{2}cos(t).$

Find the acceleration for $t=2$ seconds, $A=4,$ and $=0\mathrm{.}6.$

$3.$ Find the roots of the polynomial

$f(x)=x^5+2x^2+1$

by following the steps below

a$.$ First create a row vector with the coefficients and store in a variable called myPoly.

b$.$ Use the roots$)$ function with myPoly as an argument to calculate the roots.

c$.$ Store the roots in the variable called myRoots.

$4.$ Define an array of $3$ complex numbers and store them in a row vector variable called $z$ by following below steps

a$.$ Create one array called $x$ with three elements $-5,0$ and $9.$

b$.$ Create one array called $y$ with three elements $4,6$ and $.$

c$.$ Use the complex function to define the array of complex numbers.

$5.$ The $OR$ operator has two logical expressions as operands. The result of an $OR$ operation is true if one of the operands is true; it is false if both operands are false.

a$.$ Assign the expression $)(-4$ to a variable called $x.$

b$.$ Assign the expression $\text{'}D\text{'}={?}^{\text{'}}N\text{'}$ to a variable called y$.$

c$.$ Check if $x$ OR y is true using an appropriate MATLAB expression.

$6.$ Follow the steps below to create a triangular waveform similar to the one shown below with amplitude A and fundamental frequency $$
