Question

Matlab Help? I'm having some issues trying to figure out how to make a polar plot of the function r=2sin(3theta)sin(theta) for 0 11 years ago

Answer 1

when you multiply sin(3*t) .* sin(t)
you should use dot *
to show that you are multiplying corresponding elements.

Answer 2

also, you might want to append semi-colons to the end of each statement.

Answer 3

this should work
t=linspace(0,2*pi,200);
r=2*sin(3*t) .*sin(t);
polar(t,r);
