The reason I'm asking this is because some math expressions have more width that others for instance: \[\int_{a}^{b} sin^3(x)dx + 1/2(1+cos(2x)) ...

(a) $I=\int\cos^3(x)dx$. Trying $u=\sin(x)$, then $du=\cos(x) dx$ producing. $$\displaystyle I=\int\cos^2(x)du=\int(1-u^2)du=u-u^3/3=\sin(x)-\sin^3(x)/2+c$$.
