How to plot the same function several times with several different angles

Suppose I had the equation of y=sin(x), and I wanted to plot the function of this equation several times with angles ranging from [32.1, 46, 81]. How could I input these values into the function in order to graph all these values?

clear all
x1=[32.1, 46, 81]
x= 0:pi:x1
y=sin(x)
plot(x,y)

I thought it'd be this code, but clearly I was wrong. Thanks for any help you guys can provide.

Avoid using clear all, just use clear

x1=[32.1, 46, 81]
x= 0:0.001:0.2
y=sin(bsxfun(@times,x',x1))
plot(x,y)
