Calculator online - service solutions on-line

Calculators online > Common Engineering Mathematics Calculator

Basic or scientific calculator online for free

Perform simple operations with numbers, as well as more complex as math calculator.
Here two calculators are presented
  1. The first calculates locally in your browser as basic
  2. The second calculates locally in your browser as scientific
  3. The third calculates on the server as math

Basic calculator

The Free basic calculator allows you to perform simple operations on the calculator, such as addition, subtraction, multiplication, division. You can dial directly from the keyboard, for this first click on a region with a calculator.

You can take advantage of the fast mathematical calculator

Engineering scientific calculator allows plus more complex operations on the calculator, such as sine, cosine, arc sine, arc cosine, tangent, arctangent, power, exponent, logarithm, interest, also has operations in the memory of the calculator online. You can dial directly from the keyboard, for this first click on a region with a calculator.

Enter an expression into the calculator, which is necessary to calculate on the server

Math calculator is the most advanced (it calculates on the server). With what he knows how to work described below. Use this.

Expression ?
Example: 3^16 + sin(4*pi) - Example for calculator
Mode
Trigonometric functions in the calculator will accept degrees or radians?

Rules concern the calculator which calculates on the server

Terms of the input functions

In expression f you can do the following operations:
Real numbers
introduce in the form 7.5, not 7,5
2*x
- multiplication
3/x
- division
x^3
- exponentiation
x + 7
- addition
x - 6
- subtraction
Function f may consist of functions (symbols are given in alphabetical order):
absolute(x)
Function - absolute value x (module x or |x|)
arccos(x)
Function - arccosine of x
arccosh(x)
Function - arccosine hyperbolic of x
arcsin(x)
Function - arcsine of x
arcsinh(x)
Function - arcsine hyperbolic of x
arctan(x)
Function - arctangent of x
arctanh(x)
Function - arctangent hyperbolic of x
e
Function - e this is something that is approximately equal to 2.7
exp(x)
Function - exponent of x (same as e^x)
floor(x)
Function - rounding x downward (sample floor(4.5)==4.0)
log(x) or ln(x)
Function - Natural logarithm of x (For log7(x), must enter log(x)/log(7) (or, for example log10(x)=log(x)/log(10))
logical_not(x)
Function - Logical "not" of x
pi
Number - "Pi", which is approximately equal to 3.14
radians(x)
Function - Translated from degrees x in radians (sample radians(180)==pi)
rint(x)
Function - Integer of x
sign(x)
Function - Badge x
sin(x)
Function - Sinus of x
cos(x)
Function - Cosinus of x
sinh(x)
Function - Sinus hyperbolic of x
cosh(x)
Function - Cosinus hyperbolic of x
sqrt(x)
Function - Square root of x
square(x) or x^2
Function - Square x
tan(x)
Function - Tangent of x
tanh(x)
Function - Tangent hyperbolic of x

Why this online calculator?

Calculator onlineCalculator online - much different from a simple calculator? First, standard calculator is not convenient to carry around, and secondly - now the Internet is virtually everywhere, in this not make problems go to our website and use the online calculator.
Calculator online - how it differs from the java-calculator, and calculators for other operating systems? - Once again - mobility. If you are on another computer, you do not need to reinstall
So, use this online!
