Not able to plot a particular relation.

I have an equation as below:

k = 4*((p*sin^2(o))+(q*cos^2(o))

with p and q = 100

o ranging from 0 to 180 degree or 0 to pi

w = (k/m)^0.5 where m=5

After specifying all this I get an error while using fplot saying invalid parameter .... I used fplot as well

Remove all the "syms" call. They are not required.
