How would I find the max y value in the following fplot
mu = @(theta) (sind(theta)/(1.8925 + cosd(theta)));
fplot(mu,[0 180]);

h = fplot(...);
MAX = max(h.YData)

Is it possible to execute this command, then find out the x location of this max?

Of course. See the Answer I gave just below...

Look at the documentation and see what else you can do with fplot...
fp=fplot(mu,[0 100]);
[mxMu,imx]=max(fp.YData); % max, location
NB: Above is the maximum of the calculated points, not necessarily the functional maximum.
ADDENDUM: To avoid the warning message from fplot write your function with the "dot" operator ./ instead of just /
