hey guys, just hpoping sum1 could point me in the rite direction....i cant wrk out how to proove v^2=n^2 (A^2-x^2) from(adsbygoogle = window.adsbygoogle || []).push({});

v dv/dx = -n^2x

obviously you hav to integrate...but i dont know how they get the A into the equation??

what i hav tried is intergating both sides with recpect to x first

v dv/dx x = (-n^2x^2)/2 and given we know dv/dx . dx/ dt = -n^2x and v = dx/dt the sub in to have

.....well it brings me no where actually hence this post

thanks for you help
