i look at physics in my free time, and i just came across the rutherford scattering formula and was wondering is it necessary to memorize it?

The important thing to take away from the formula is the [itex]1/(1-cos \theta)^2 [/itex] dependence of the scattering cross-section which is a signature of scattering from point-like objects.

the rutherford scattering formula is

N(cita)=(NntZ^2*e^4)/{[(8pi*epsilon)^2]*(E^2)sin^4(cita/2)} right?

because i don't see 1/[1-cos(cita)]^2...

Hint: browse through a list of trig identities.

so sin^4(cita/2)=[1-cos^2(cita)]/2={1-[1+cos(2cita)]/2}/2?

The differential cross-section is [itex]dN/d \Omega[/itex]
