yeeh im sure.. to clarify : the integral of : "[Ln of (x squared minus 4)] divided by [square root of (x squared minus 4)]"

hey i need help the question is integrate : (Ln(x^2-4))/(x^2-4)^(1/2) dx before that it asks to show the integral of x/(x^2-4)dx = (x^2-4)^1/2

hmm yeeh i guess soo.. thats same with fitz.. n yeh patel does hav the harder ones.. its just the book gets so awkward sometimes.. patel seems like a bit of a weirdo lol no offence to him

jst a quick question.. wat exactly is ur HSC aligned mark and wat determines it.. also wats the general relationship between ur school assessment mark, ur aligned mark, n ur scaled mark

okay wow thanx heaps for u answer n yeeh it definitely helped.. jst hope i didnt waste ur time

ohh thats a typo sorry i meant T,P,Q so the question is PQ and RS are common tangents to two intersecting circles. IF T is one of the points of intersection of the two circles, prove that the circles through T,P,Q and through T,R,S touch eachother this is from fitz by the way Q8

hey i need help with a circle geo question PQ and RS are common tangents to two intersecting circles. IF T is one of the points of intersection of the two circles, prove that the circles through T,P,W and through T,R,S touch eachother can anyone help ??
