this is simple:
ax^2+bx+c=0
x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}

how we can proof Cauchy–Schwarz inequality for these two complex numbers?
z=a+ib
w=c+id
in the case of triangle inequality
|z+w|\le |z|+|w|

this is all about
initial velocity v_i
final velosity v_f
acceleration constant a
time t
relation between them is
v_f=at+v_i
there are two types of displacement
velocity constant that is...

this is wave function \Psi{(r,t)}=Ae^{i(kr-\omefa t)}
i know what is wave vector k and angular frequency \omega
but i don't know what r position ad time t means

this is simple of wave function:
\Psi{(\vec r, t)}=Ae^{i(\phi+\vec k .\vec r - \omega t)}
\Psi{(\vec r, t)}=A|\cos{(\phi+\vec k .\vec r - \omega t)}+i\sin{(\phi+\vec k .\vec r - \omega t)}|

3x y=15
4x-3y=7
xy=\frac {15}{3}
xy=5
x=\frac {7+3y}{4}
\frac {7+3y}{4}y=5
\frac {3y^2){4}+\frac {7y}{4}-5=0
a=\frac {3}{4}
b=\frac {7}{4}

is there any other ways to solve this natural logarithm: \ln {(a b)}
for example
\ln {ab}=\ln {a} \ln {b}

2^y=x \to \log_2 {x}=y
note: \log_2 {x}=\frac {\log_{10} {x}}{\log_{10} 2}
exaple: 3^2=9 \to \log_3 {9}=2
