[QUOTE="Purple Baron, post: 4969416, member: 534443"] [h2]Homework Statement [/h2] derive an equation for the solid angle for a Rutherford scattering detector given a detcor window area of [itex]A[/itex] and a distance to the detector of [itex]D[/itex] for some scattering angle [itex]\phi[/itex] given that [itex]d\Omega =2\pi sin\phi d\phi[/itex] [h2]Homework Equations[/h2] [itex]d\Omega =2\pi sin\phi d\phi[/itex] [itex]A=Dd\phi [/itex] [h2]The Attempt at a Solution[/h2] integrating [itex]d\Omega =2\pi sin\phi d\phi[/itex] to get solid angle gives [itex]\Omega =\frac{2\pi A}{D}\int sin\phi d\phi[/itex] howver this gives a negative value due to the integral of sine and shouldn't soild angle be positive? Is this correct or am i missing a step? Thank You [/QUOTE]
