Question

solve all questions simply by using matlab.

write all step here please

1Normal 1 No Spac Heading1 Heading 2 DISCUSSION Solve all tasks given below: 1. Consider function f(x) 3.5-0.5x cos(6x) for the value of x between -2.0 until 4.0. Draw the plot in dash line and in red colour, Label the title and all axes. 2. Consider the following functions for 0sxS pi: x() 10e0.St sin(3t +2) y(t) 7e-04t cos(5t - 3) (a) Draw both graphs on the same plot. Differentiate both graph with different line properties, and label each graph. (b) Draw both graphs on separate plot but within the same figure window using subplot command.

Answer 1

1.The matlab command is given below

x=[-2:0.1:4];
y=(3.5).^(-0.5.*x).*cos(6.*x);
plot(x,y,'-r')
grid on
xlabel('X axiss')
ylabel('Y axiss')
title('ploting of polynomial graph')

2(a).Both graph on the same plot

t=[0:0.1:pi];
x=10.*exp(-0.5.*t).*sin(3.*t+2);
y=7.*exp(-0.4.*t).*cos(5.*t-3);
plot(t,x,'-r',t,y,':g') % - is used for solid line and : is used for dotted line r for red colour and g for green
grid on
xlabel('x-axiss')
ylabel('y-axiss')
title('plottig of graphs')
legend('y','z')

2(b). using sub plot comand

subplot(2,1,1)
t=[0:0.1:pi];
x=10.*exp(-0.5.*t).*sin(3.*t+2);
plot(t,x,'-r')
title('subplot 1: x(t)')
subplot(2,1,2)
t=[0:0.1:pi];
y=7.*exp(-0.4.*t).*cos(5.*t-3);
plot(t,y,':g')
title('subplot 2: y(t)')
