Angles - Computational trigonometry
    ANGLES is a program to help students learning simple trigonometry. It contains a lot of problems to be solved using rules, transferors, and calculators on the screen. An author tool for teachers to prepare new problems is built in. Although there are similar but more sophisticated programs on the market, this one offers the advantage of simplicity. We are planning to provide some multimedia extensions to it.
