# Normalizing a simple wave function

Classical Mechanics Level 3

Given below is a wave function

$${\psi}(x)$$ = A( $$\sqrt{15}{\psi}_{1}(x)$$+$$\sqrt{7}{\psi}_{2}(x)$$+$$\sqrt{99}{\psi}_{3}(x)$$)

Where $${\psi}_{1}(x)$$ , $${\psi}_{2}(x)$$ ,$${\psi}_{3}(x)$$ are orthogonal.

Find the normalization constant A upto 4 decimals.
