where $=2f.$ Calculate the current $1$ for the circuit shown if the supply voltage $V=$

$80$volts, $f=50Hz,L=400{10}^{-1}H,R=6,$ and $C={40}^{-10-F}F.$

The acceleration of a spring is described by

$a=-A*cos(t).$

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

Find the roots of the polynomial

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

by following the steps below

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

wxPalx

b$.$ Use the motsf$)$ function with pu&Rolx as an argument to calculate the roots.

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

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.

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 $(7-4)$ to a variable called $x.$

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

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

Follow the steps below to create a triangular waveform similar$-$to the one shown

below with amnlitude A and fundamental fremuenev $a$

a$.$ Assign $5$ to the variable $A($amplitude$).$

b$.$ Assign $0\mathrm{.}3$ to the variable $T($period$).$

c$.$ Calculate the frequency using the following formula and assign to the

variable f$.\text{'}-).$

d$.$ Calculate the angular frequency $$ using the formula $=2$ f and assign to

variable omega.

e$.$ Create the vector time named $t$ using linspace command with $1001$ points in the

range from $0$ to $1.$

f$.$ Create the vector voltage named $v$ using the following equation: $v=A**$ tri $(t),$

where the function sawtooth can be used in MATLAB to represent the triangular

waveform.

g$.$ Create the vector named $y$ mod using the following equation: $v_{-}$mod $\frac{?}{a}=bs(v).h.$

Plot voltage $(y-$axis$)$ against time $(x-$axis$).$

i$.$ Add title, $x-$axis and $y-$axis labels as follows:

Title: 'Triangular Waveform'$=$

x$-$axis label: 'Time $($seconds$)\text{'}$

y$-$axis label: 'Voltage $($volts$)\text{'}$
