This website features a web-based integral calculator that allows the computation of integrals in the user's browser. The integral calculator supports both indefinite integrals (antiderivatives) and definite integrals. If the user enters "cos(x)", the answer "sin(x)" will be given. The calculator also supports far more complex mathematical expressions including functions composed of trigonometric functions, hyperbolic functions and exponential functions (and their respective inverse functions). When computing definite integrals, improper integrals with limits such as (negative) infinity are supported as well. The integration variable can be selected by the user, and the integral calculator can optionally simplify all input and output expressions. Calculations are performed using the Computer Algebra System (CAS) "Maxima", which is one of the oldest and most robust CAS. Both the user's input and the answers are displayed as graphical formulas using MathJax. Calculations can be shared with other users. more info >>

This unique fractal generator allows you to design unique and original fractal icons with dihedral symmetry - the software employs hyperbolic iterated function systems of affine transforms and is fully customisable - diverse predefined colour palettes allows to obtain beautiful fractal icons, without bothering with colour scales - Symmetry can be chosen from 3 to 60, invariant by reflection or by rotation only - In our knowledge it is the single fractal generator of this quality directly available on the internet, not requiring any download, but working in html5 on any internet connected platform, from tablets to pc to xbox - Produce your unique fractal icon to say happy birthday to a friend, create an astonishing logo for your activity, or simply to explore fractal mathematics and the infinite possibilities of affine transforms and hyperbolic iterated function systems more info >>
