It lets you find the acceleration function.

Thank you trebla! One last question: The lows of a point P on the rim of a circular wheel of unit radius rolling on a straight line is defined by: x=(theta) - sin(theta) y=1-cos(theta). Find the volume of the solid formed by rotating the arch under the curve, for 0<=(theta)<=2pi, about the...

Thanks jyu, ingenious (Y)

The rectangle OABC, where O(0,0), A(a,0), C(0,c) is cut through by a continuous, smooth, differentiable curve y=f(x). The region below y=f(x) is rotated about he side OA while the region above y=f(x) is rotated about the side BC. If the volumes of the two solids are equal, show that the two...

My friend needs a biology tutor (one on one) to guide him through. Anyone interested?

Trials in 7 weeks?

This is what makes sense to me, but I suppose you can answer the question in both ways as long as you explain your process?

There's this old green book by Phoenix, has exam questions sorted into questions with working, etc.

Hmm okay, cool.

If a question goes "blah blah, find the population in 99 days" and you get some answer that would usually round up (0.5~0.9), do you round up? Because technically you can't have more than half a person.

Doesn't the more people in the cohort = more 99.95's

People at my school say yes, but their marks say otherwise. Ridiculous question if you ask me.

Whut about a garbageman

Yeah, I don't seem to be able to find them.

I've gone and compiled most papers from 4unitmaths.com but I was wondering if anyone has the solutions to these papers (any would help)? (Sidenote: Am I allowed to post websites like I just did above?) Love you guys
