I'll appreciate any suggestions or comments you all have. f(t) * [f"(t) + C] = K where f(t) is a real-valued function of a single real variable, f"(t) is the second derivative of this function w.r.t. t and C and K are positive real constants. We also know that f(0) = d > 0 and f'(0) = 0. Help? -- Roger Noe ihnp4!ihlts!rjnoe
