ok this is what i mean. For exmaple take this problem that I asked for help with before

Naturalists find that the populations of some kinds of predatory animals vary periodically. Assume that the population of foxes in a certain forest varies sinusoidally with time. Records started being kept when t = 0 years. A minimum number, 200 foxes, occured when t = 2.9 years. The next maximum, 800 foxes, occurred at t = 5.1 years

use the formula I provided in other post

using points in problem that are max and min

max (A,B) = (5.1, 800)

A = 5.1

B = 800

Min = (C, D) = (2.9, 200)

plug and chug and you get the sinusodial funciton.

my question was how to rearange that formula for A, B, C, D, X, given all the other variables

you can just show me the formula if you want sense the work is probably a lot

I really need to know how to rearange the formula given all but X and the other formulas for A, B, c, D, or a second priority but is still something I need to know how to do but don't know how to

thanks
