d/dx(sec x) = d/dx((cosx)^-1) = -(cosx)^-2 * -sinx =sinx/cos^2x =1/cosx* sinx/cosx =secxtanx therefore the integral of secxtanx is secx

well i reckon i got somewhere around 67% raw in the exam ( worst 4 unit paper results i ever got =[) and i ended up with an aligned mark of 91

dont worry, i basically procrastinated until the holidays before the exams and i ended up with a pretty good uai

y=-x-3 (1) x^2=12y (2) (1) into (2) x^2=12(-x-6) x^2= -12x-36 x^2 + 12x + 36 = 0 discriminant= b^2 - 4ac = 12^2 - 4*36 =0 therefore tangent as it only has one point of contact now to find the point of contact lets solve x^2 + 12x +36 = 0 which is a perfect square so: (x+6)^2=0 so x=-6...

All right thanks everybody for your help someone told me it was a 40 hour week so this is much better to hear =]

im going to be doin this course this year and i was just wondering how many hours a week should i be expecting to spend in lectures and tutes, etc? thanks

a torus is like a doughnout, it is formed by rotating a circle around a certain line. then you can use slicing or shells i always choose shells when i can. <3 shells

partial fractions is not used here, at least in my solution id split the numerator in both. 1) S (2x+3)/sqrt(4-x^2) dx = S 3/sqrt(4-x^2) dx + S 2x/sqrt(4-x^2) dx which are both simple integrals = 3asin(x/2) - 2sqrt(4-x^2) 2) split the integral into S 3/sqrt(x^2+2x+10) dx - S 2x+2/sqrt(x^2 + 2...

yeah i was thinking the exact same thing yesterday i think the fact he wasnt willing to not play in the 1st new zealand test match in order to most probably save the indian series with the overrate thing shows that to me. i wouldn't call him a woefull captain though. his still learninghow to...
