We can calculate the gradient of a tangent to a curve by differentiating. In order to find the equation of a tangent, we: Differentiate the equation of the curve Substitute the \(x\) value into the ...

This paper is concerned with the critical curve of non-Newtonian polytropic filtration equations coupled via the nonlinear boundary flux. We obtain the critical global existence curve by constructing ...

Transactions of the American Mathematical Society, Vol. 350, No. 4 (Apr., 1998), pp. 1681-1701 (21 pages) Odani has shown that if deg g ≤ deg f then after deleting some trivial cases the polynomial ...

Many complicated advances in research mathematics are spurred by a desire to understand some of the simplest questions about numbers. How are prime numbers distributed in the integers? Are there ...

Growth charts are used in pediatric medicine to plot anthropomorphic measurements over time, serving as a screen for diseases related to a patient's nutritional and general health status. Whereas ...

A linear demand curve is a line representing the relationship between the demand for a product or service and its price. Everyone knows that sales are proportional to price: The more you charge for an ...
