Roots
The calculator has three root functions: a square root (key ‘r’), cube root (key ‘v’) and general root (keys shift, ‘^’). The first two find the root of the expression following. The third finds the xth root of y, where x is the expression preceeding the root and y the expression following. Here x need not be an integer. It can be any complex number.
Powers
The calculator has three power functions: a square (key ‘q’), a cube (keys shift, ‘u’) and general root (key ‘^’). The first two find the square or cube of the preceding expression. The third finds the yth power of x, where x is the expression preceeding the root and y the expression following. Here y can be any complex number.
Inverse
The inverse button (key ‘i’) allows you to find the inverse, 1 / x, of the preceding expression x.
Logarithms, antilogarithms and exponential function
The log button (key ‘l’) and ln button (key ‘L’) let you find the base-10 and natural (base e) logarithm of the following expression. To get antilogarithms, use the 10x button (keys shift, l) for base 10 and the exp (exponential function) button (keys shift, e) for base e. In both cases the antilogarithm of the following expression is found.
You can evaluate logarithms and antilogarithms for any complex number.
Only the general power and root functions are available when not using decimal notation.
