You came to the right place.

This is a calculator site.

How lucky are you?

BUMMER!      LOL    :D

Thanks Bertie :))

Use atan

it is the same thing

CONGRATULATIONS JILLYBEAN :))

Yes I like that Chris, thanks.

Good one Chris :))

Thanks Chris. 

Never forget that there is often more than one solution with trigonometry. :)

You would think I should have learned this lesson by now - I guess I haven't.  :))

A population of 100 rabbits increase at an annual rate of 22%. How many rabbits will there be in 5 years

FV=100(1+0.22)^5

Just use the quadratic formula

This post is getting a little old now but i thought someone might know how this can be done.  It seems a faily obvious thing that a mathematician would want to know.

You could type in an equation with unknown coefficients etc, add the points that it should go through and have some possibilities thrown out - or maybe told that there is insufficent data. (maybe with a reason)

Surely there is a program around that will do this.
