SECTION 1.9-CoMPUTING wITH MATLAB 1.46 Determine the numeric value of x in each of the following MATLAB instructions: (a) t pi/3; x cos(t) (b) t 1:4; x 32 sin (t)

Solution

MATLAB CODE :-

clear
clc
i =1;
disp(\'x = cos(t)\ \')
t = pi/3
x1 = cosd((t*180)/pi)% a) t = pi/3 ; x = cos(t)
sprintf(\'t = pi/3 \\t \\t x = cos(t) = %f\',x1);

%%

for t = 1:1:4 % b) t = 1:4; x = 2* sin(t)
t1(i) = t;
x2 = 2*sind((180*t)/pi);
x(i) = x2;
i = i+1;
end
disp(\'x = 2*sin(t)\')
t1
x
sprintf(\'t = %d\ \',t1);
sprintf(\'x = %f\ \',x);

OUTPUT : -

x = cos(t)\

t =

1.0472

x1 =

0.5000

x = 2*sin(t)

t1 =

1 2 3 4

x =
