differentiate cubics

Added Jul 10, 2012 by qubiq1234 in Mathematics

simple tool to allow learners to explore the result of differentiating cubic functions to see if they can discover the rules for differentiation of polynomials.

Intensity of gamma radiation

Added Jun 25, 2012 by qubiq1234 in Physics

A little widget to calculate radioactive intensity (I) given: n = number of photons/sec f = frequency of radiation in standard form r = radius (distance from source)


radioactive decay

Added Jun 25, 2012 by qubiq1234 in Physics

modeling the decay graph of a radioactive isotope of initial mass M, with a half-life of T

highest common factor

Added Sep 14, 2011 by qubiq1234 in Education

finds HCF of (a,b)


visualise and find the 3D vector from A to B

Added Sep 14, 2011 by qubiq1234 in Education

finds the diplacement vector AB given the coordinates of A and B, showing a diagram and finding magnitude.

vector addition and resultants

Added Sep 14, 2011 by qubiq1234 in Education

Adds two vectors given in the form: ( horizontal ) ( vertical ) and returns the vector in for (x,y) together with a vector addition diagram.


perpendicular vectors and resultants

Added Sep 14, 2011 by qubiq1234 in Education

Adds two perpendicular vectors. Encourage learners to realise that Pythagoras and trigonometry can be used to find the magnitude and direction of the resultant.

magnitude and direction of vectors

Added Sep 14, 2011 by qubiq1234 in Education

Works out the magnitude and direction of a vector give in form: ( horizontal ) ( vertical )


quadratic plotter

Added Sep 13, 2011 by qubiq1234 in Education

A simple widget to facilitate learners' exploration of the effects of a, b and c in the general quadratic function.

quadratic factorizer

Added Sep 13, 2011 by qubiq1234 in Education

A simple widget to factor a general quadratic and plot its graph to assist learners making hypotheses about the relationship between factors and roots.


vector plotter

Added Sep 13, 2011 by qubiq1234 in Education

Plots a vector given horizontal and vertical components: ( horizonatal ) ( vertical )

divisibility checker

Added Sep 10, 2011 by qubiq1234 in Education

A really simple little tool to check whether one number divides another to help learners begin to spot divisibility rules for themselves.
