We’ve just launched our first facebook app, Space Birthday. This app will tell you how many years have passed on other planets since you and your friends were born – that is, how many time Mercury, Venus, Mars, Jupiter and so on have circled the sun.
We’ve just started a new website, GraphPower.com. Our goal is to use that website to provide great calculus software. First up is an online integrator for definite integrals. Just by itself, it should be a great help for calculus students who want to check their work, but we’ll be rolling out a whole bunch of other integrators really soon.
