A Catalyst article about diamonds. The element carbon exists in a number of allotropic forms, but diamonds have always held a special allure, whether it be for their hardness or for their transparency. The article examines how they can be made artificially and looks at some of their uses.

In this resource from the DfE Standards Unit, students convert functions into an appropriate form for differentiating or integrating and then differentiate and integrate negative and fractional powers of x. Before starting the activity students should be able to differentiate and integrate polynomial functions and...

Mathcentre provide these resources which cover aspects of differentiation. They include an introduction to differentiation, a technique used to calculate the gradient or slope of a graph at different points, a table of common functions and their derivatives, as well as linearity rules which, when used with a table...

Mathcentre provide these resources which cover aspects of differentiation which are suitable for students studying mathematics at A Level, as well as those students for whom mathematics is an integral part of their course. Some of the topics covered include, differentiation from first principles, a table of common...

Mathcentre provide these resources which cover aspects of differentiation, often used in the field of engineering. They include an introduction to differentiation and its uses, a table of common functions and their derivatives, as well as the rules used to enable the differentiation of a wide range of functions....

This excel file plots both quadratic and cubic functions along with the graphs of their first and second differential equations.

By specifying the values of the coefficients of either the quadratic or cubic function...

This RISP activity introduces the subject of differentiation. Rather than start from first principles or learning a rule, the activity suggests using a graphing package to generate data. Starting with a quadratic graph, students find the gradient of the curve using a straight line graph and are encouraged arrive at...

This interactive resource, produced by the University of Leicester, is designed to enable students to explore the differential function of a polynomial and conclude by forming a generalisation.

An instruction page explains to students that they should draw a polynomial. Then by sliding the slider the...

This resource contains eleven problems requiring students to explore where turning points occur, match statements about functions to statements about derivative functions and gradients of graphs at specific points on the curve, explore the tangent and normal to a curve, suggest a possible graph given information...

Practical use of diffraction gratings include emission spectra as well as explorations of the wave-particle nature of light and the interference patterns that emerge.
