p=0.5*(1-x^2)/((1+(x^2)-2*x*cos(t))^(3/2))

here t varies from -pi to pi x is a constant like for example 0.1

What about:

x = 0.1;
t = linspace(-pi, pi, 200);
p = 0.5 * (1 - x.^2) ./ ((1 + x.^2 - 2 .* x .* cos(t)).^(3/2));
plot(t, p);

Such methdos are explained exhaustively in the Getting Started chapters of the documentation and help plot offer detailed information also.

x = 0.1;
t = -pi:.01:pi;
p=0.5*(1-x^2)./((1+(x^2)-2*x*cos(t)).^(3/2));
plot(t,p)

I'm guessing you really mean plot p as a function of t
