How to produce a plot on the x and y axes

Hello friends,

I want to produce a plot, there is a problem in line 5.

Thanks for the helpers

clc;

w=8500;
teta = 39.29:51.57;
F=-w/(2*sin(teta));
                                                                                  
plot(teta,F)                                               
grid

w=8500;
teta = 39.29:51.57;
F=-w./(2*sin(teta));    % <-- element by element operation 
                                                                                  
plot(teta,F)                                               
grid
