SHORT FORMULA - MATHEMATICS - STRAIGHT LINE

Distance Formula :

$d\, =\, \sqrt {{({x}_{1}-{x}_{2})}^{2}+{({y}_{1}-{y}_{2})}^{2}}$

Section Formula :

$x\, =\, \frac {m{x}_{2}\pm n{x}_{1}} {m\pm n},\, y\, =\frac {m{y}_{2}\pm n{y}_{1}} {m\pm n}$

Angle between two straight lines :

$tan\theta \, =\, \left | {\frac {m1-m2} {1+m1m2}} \right |$
