Introduction: In this lab we have learnt how to implement basic formulas and identities in Matlab.

Tasks:

Activity# 01: i)

Use arbitrary value of theta and verify that sin^2(theta)+cos^2(theta)=1

clc; clear; close all; theata=45; theata1=45*(180/pi); x=(sin(theata1)*sin(theata1)+cos(theata1)*cos(theata1))

clc; clear; close all; theata=30;

theata1=(2/180)*pi; z=sinh(theata1) y=(exp(theata1*j)-exp(-theata1*j))/2*j

clc; clear; close all; theata1=(45/180)*pi; z=tan(theata1) y=(sqrt(1-cos(2*theata1)/(1+cos(2*theata1))))

clc; clear; close all; t=input('enter value of t') y=exp(-0.2*t)*(cos(t)+j*sin(t))

ACTIVITY# 02

clc; clear; close all; z=3+j*4 j=4;

a=3+4j b=3+4*j c=3+j*4

clc; clear; close all; w=10*pi; T=0.1; G=1+j*w*T; V=1/(1+j*w*T); A=abs(G) B=phase(G) C=abs(V) D=phase(V)

clc; clear; close all; w=2*pi; G=1-j*w/j*w*(1+j*2*w); A=abs(G) B=phase(G)

ACTIVITY #03

clc; clear; close all; x=-1:1:1 y=1+exp(-x)/1-exp(-x)

clc; clear; close all; t=-1:1:1 y=2*exp(-t)-3*exp(-2*t)

ACTIVITY#04:

clc; clear; close all; A=[2 5 -3;3 -2 4;1 6 -4]; b=[6;-2;3]; x=inv(A)*b

clc; clear; close all; t=1:1:10; T=2; k=0.75; w=k*(1-exp(-t/T))

i.

clc; clear; close all; t=0:0.05:5; y=(exp(-t)).*(sin(pi*t))

ii.

clc; clear; close all; t=0:0.05:5; y=(sin(pi.*t.*t))/(t.*t)

PLOTING:

clc; clear; close all; t=linspace(0,10,50); T=2;k=0.75; w=k.*(1-exp(-t/T)); subplot(3,1,1) plot(t,w) k=3; w=k.*(1-exp(-t/T)); subplot(3,1,2) plot(t,w) k=5; w=k.*(1-exp(-t/T)); subplot(3,1,3) plot(t,w)

clc; clear; close all; t=linspace(0,10,50); k=3;T=2; w=k.*(1-exp(-t/T)); subplot(3,1,1) plot(t,w) T=0.5; w=k.*(1-exp(-t/T)); subplot(3,1,2) plot(t,w)

T=4; w=k.*(1-exp(-t/T)); subplot(3,1,3) plot(t,w)...
