Normal: $\delta,\Delta$, with boldsymbol $\boldsymbol{\delta},\boldsymbol{\Delta}$

### Small primes issue

Standard $\delta^{\mu'}_{\nu'}\delta^{\nu'}_{\mu''}=\delta^{\mu'}_{\mu''}$

\displaystyle $\delta^{\displaystyle\mu'}_{\displaystyle\nu'}\delta^{\displaystyle\nu'}_{\displaystyle\mu''}=\delta^{\displaystyle\mu'}_{\displaystyle\mu''}$

\textstyle $\delta^{\textstyle\mu'}_{\textstyle\nu'}\delta^{\textstyle\nu'}_{\textstyle\mu''}=\delta^{\textstyle\mu'}_{\textstyle\mu''}$

With \prime $\delta^{\mu^\prime}_{\nu^{\prime}}\delta^{\nu^{\prime}}_{\mu^{\prime\prime}}=\delta^{\mu^{\prime}}_{\mu^{\prime\prime}}$

With \prime and \displaystyle $\delta^{\mu^{\displaystyle\prime}}_{\nu^{\displaystyle\prime}}\delta^{\nu^{\displaystyle\prime}}_{\mu^{\displaystyle\prime\prime}}=\delta^{\mu^{\displaystyle\prime}}_{\mu^{\displaystyle\prime\prime}}$

Standard 16px fonts

$\delta^{\mu'}_{\nu'}\delta^{\nu'}_{\mu''}=\delta^{\mu'}_{\mu''}$

### Magnify an equation

Standard

$\Phi_{ \mu} (P) = \frac{1}{c} \int \frac{[J_{\mu}] dV}{r}$
