Simple Question: How to Plot a Function over an Interval (Details in Body)
显示 更早的评论
Hello, it's been too long since I've used Matlab.
Could someone please help me with the following? I tried looking online but other solutions didn't help me for some reason. Thanks in advance!
t = 0:0.01:pi % Theta from 0 to pi
tm = sqrt(44*cos(t).^2 + 44*cos(t)*sin(t)+29*sin(t).^2)
plot(t, tm(t))

t = 0:0.01:pi; % Theta from 0 to pi
%
tm = sqrt(44*cos(t).^2 + 44*cos(t).*sin(t)+29*sin(t).^2); % traction magnitude eqn derived on paper
plot(t, tm)

Alternatively, you can also use fplot() to symbolically plot the function 
over the specified interval 
for t.
over the specified interval for t.syms t
tm = @(t) sqrt(44*cos(t).^2 + 44*cos(t).*sin(t) + 29*sin(t).^2);
fplot(tm, [0 pi])
grid on
title('tm(t) from 0 to \pi')
xlabel('t');
ylabel('tm');
