The ancient Egyptians were the first civilization to develop and solve second-degree (quadratic) equations.

His first assignment was to develop equations for the state of materials at high temperatures, pressures and densities.

Jandera and Fischer developed equations to describe the dependence of retention behavior on the change in micellar concentrations.

They can be used to explain, predict, and test, or to develop computer programs or mathematical equations.

Lotka developed paired differential equations that showed the effect of a parasite on its prey.

The goal is to develop dynamical equations for the collective part.

They developed partial differential equations which modeled the shapes created by termites when constructing their nest.

More broadly, it runs counter to a trend in other jurisdictions to develop equations for child support.

Or it is with me at any rate, although I hope someday to have enough data to allow me to develop equations for it all.

Mathematical topics (mainly trigonometry and elementary calculus) were taken up when necessary for developing theoretical equations.
