Hello,
I was wondering if there was a quick clean and easy way to make a function input multiple values of x, such as 0, .25 ,.5, .75, 1 and then plot these five curves out on the same plot. I know how to do it manualy by create 5 different functions and naming them slightly differently, but I was wondering if there was a quicker/cleaner way of doing it?

Those are 5 scalars, not 5 functions or curves. You can use "hold on" to plot multiple curves on one plot.
plot(x1, y1);
hold on;
plot(x2, y2);
plot(x3, y3);

In plot(x,y), if x and y are matricies, a line will be drawn for each column of the inputs. There are additional ways to get multiple lines out of one set of inputs and that's all examples in the documentation.

You can use plot in one statement
plot(X1,Y1,...,Xn,Yn) plots multiple X, Y pairs using the same axes for all lines.

A = [10 20 30 405 50] ;
th = linspace(0,2*pi) ;
X = zeros(length(A),length(th)) ;
for i = 1:length(A)
X(i,:) = A(i)*sin(th) ;
end
plot(th,X)
