This is the code I am working with and it shows error, Whats the problem and what can be done to solve it?

t = linspace(-100*pi, 100*pi); %define the range you are plotting over

x = (t-2)/(t+2);

y = sin(t);

z = log(9-t.^2);

plot3(x, y, z);

axis equal

Hello Ajay,

You are getting the error as x,y,z are not of the same length. x is a single element vector. if you want to do (t-2)/(t+2) to every elememt use (t-2)./(t+2) The code goes liked this

t = linspace(-100*pi, 100*pi);   %define the range you are plotting over
x = (t-2)./(t+2);
y = sin(t);
z = log(9-t.^2);
plot3(x, y, z);
axis equal

Read about element by element operations.

t = linspace(-100*pi, 100*pi);   %define the range you are plotting over
x = (t-2)./(t+2);  % <----- element by element divison
y = sin(t);
z = log(9-t.^2);
plot3(x, y, z);
axis equal
