This short task contains two questions on applying trigonometry.

The topics covered are:

• Linking sine, cosine and tangent
• Using Pythagoras to determine a length in a triangle and then give the tangent of an angle in surd form
• Using the Pythagorean identity sin2(x) + cos2(x) = 1...

From Rolls-Royce, these materials are designed to show students the exciting range of careers that are available for students with science, technology, engineering or mathematics skills.

Carom Maths provides this resource for teachers and students of A Level mathematics.

The Fibonacci sequence is an example of a linear recurrence relation (LRS). A matrix is used to calculate future terms, as well as running the sequence backwards to see how many zeroes appear. Algebra is used to prove the...

The mathematical solution explains how to find the value of the first and second derivatives of a given function at specific values for x. The function is presented in the form of algebraic fractions which needs to be converted to index notation and the chain rule used to find the differentials.

In this task students analyse a key prediction made during an environmental crisis on the streets of London; that they would be nine foot deep with horse manure within 50 years. Students research any required data, make estimates and perform calculations to determine...
