Evaluate mathematical expressions and formulas. Use a wide set of mathematical functions: trigonometric, hyperbolic,invers trigonometric, invers hyperbolic, logarithmic, antilogarithmic, boolean, statistic and others. You may insert functions into expression in simple manner using the main menu of the program. Besides, you may select a part of the expression and then use 'insert' menu. In this way the selected part will be inserted into new function as an argument! Absolutely necessary for everyone who is interested by mathematics.
