I recently saw that the sine function could be approximated greatly by [1-(((2/pi)*x)-1)^2]^(pi/e) for the range (0,pi) does anyone have any other strange functions like this that may satisfy some of the other transcendentals? (It'd be nice to find out how to derive the above formula too)

Thanks marin, However I already know of those methods, notice I never asked for methods but rather for papers that have been published, or any other source that I could use for research, on the exact number of zeros given any arbitrary interval on any given continuous function, I'm just having...

I'm in need of sources, articles, mainly anything that can provide information on finding the exact number of zeros for any given continuous function, thanks in advance.

that's about it, my first post states out the entire question, no initial values, at all...and thanks by the way.

so then this question doesn't have a numerical solution, only one in terms of L?

Right, following the chain rule I do get dv/dt=120*L^2, I tried before to get L in terms of t, via integration but of course that gives 5t^2+C whereas C would pose as a problem since I've no way of obtaining it, so I can't get a numerical solution I just get a solution in terms of L...

I'm having some trouble with the following question, it was on a test previously and I haven't been able to figure it out :/ Let V=4*L^3 cm^3, where dl/dt=10*t cm/s. Find dV/dt at t=0.1 second
