Aligning and spacing

Boundaries of integration

Standard way:

${\displaystyle \int _{0}^{\infty }e^{-ax^{2}}\,dx={\frac {1}{2}}{\sqrt {\frac {\pi }{a}}}\qquad {\text{and}}\qquad \iiint _{\mathbb {R} ^{3}}\langle \Psi |\Psi \rangle \,dx\,dy\,dz=1}$

Preferred way:

${\displaystyle \int \limits _{0}^{\infty }{\frac {\sin x}{x}}dx={\frac {\pi }{2}}\qquad {\text{and}}\qquad \iiint \limits _{\mathbb {R} ^{3}}e^{-a(x^{2}+y^{2}+z^{2})}\,dx\,dy\,dz=\left({\frac {\pi }{a}}\right)^{3/2}}$
