[2011-06-19] Miguel: Cannot solve expressions when a constant multiplies a variable, like 8-2x²=0 (it will solve 4-x²=0 though). Will change my rating if this is fixed. |

[2011-03-08] James : Doesn't remember degree/Radian choice when restarting phone. Animation when answer appears is annoying - would be better to have a two line display. |

[2011-02-19] ES: Can a formula be entered with various unknowns and then solve for the unkown? Will the solver rearrange the equation automatically? |
