The program is named CaRevol Jet and allows to execute engineering calculations as the formulas, makes fulfillment of all operations with complex and actual numbers. This addition, multiplication, subtraction, division of complex numbers. Exponentiation, taking the logarithm, calculation of trigonometrical and inverse functions from complex arguments. Quantity of brackets and the enclosure is not each other limited. Functions of representation of complex numbers in the trigonometrical form - module and argument of a complex number. 12 functions of transformation of measures of angles radians (rad), degrees (deg), grads (gra), turnovers (cycles). It is possible to insert a built-in manual from 20 of constants on physics and mathematician, which also into the formulas. The outcome of the last evaluation is saved as a variable for further calculations and is inserted as a constant into the consequent formulas. This version is the first release on CNET Download.com.
