Constant, Identitiy f, Absolute, Square root, square, and Cube root function * * * * * There are four basic functions and these are addition, subtraction, multiplication and division.
A binary operator is simply an operator that works with two operands (for example, two numbers). The binary operator is usually written between the two operands. Examples include the familiar operations of addition, subtraction, multiplication, or division - for example, in: 2 + 3 the "plus" is the binary operator, which works on the two numbers written on either side of it. What is an operator: Basically a function (calculation rule), written in a special way.
The inverse function of multiplication is division.
http://www.wolframalpha.com/input/?i=integrate+exp(x^2) The solution lists an "imaginary error function". This means that the integral can NOT be expressed as a finite number of the so-called elementary functions (that is, as any combination of addition, subtraction, multiplication, division, trigonometric functions, inverse trigonometric functions, exponential function, natural logarithm). The site mentioned also shows a series expansion.
The four basic operations are:+ for addition- for subtraction* for multiplication/ for divisionTo calculate an average, you can use the average() function. Type:=average(then select a range of cells with the mouse. Finish by closing parentheses.
