Calculate using Google Calculator

Few days ago, I post an article how we finding serial key using Google. Let's learn another Google Searching technique. Most of the time we are using a piece of paper or calculator to calculate a mathematical expression. Instead of using a piece of paper, calculator or any software for calculation, you can now solve mathematical problems with Google’s built-in calculator function. Not only you can search the web with Google but also you can use it as a Calculator. It can calculate both basic and advance math problems. You want to add up a list of numbers, convert from miles to kilometers or evaluate some other mathematical expression? Simply enter the expression you’d like to evaluate in Google’s web search box and click the Enter key or click the Google Search button.

Thinking about how to use it? See below examples:

Sin, cos, tan,                 trig functions(arguments                       cos(pi/3)

sec, csc, cot                 are assumed to be in radians)                cosine(pi/3)

arctan, arccsc, etc.        inverse trigonometric functions              arcos(.5)

sinh, cosh,

tanh, csch,

arsinh, arccsch, etc.       hyperbolic functions                              cosh(6)

ln                                  logarithm base e                                   ln(16)

log                                logarithm base 10                                  log(16)

lg                                  logarithm base 2                                    lg(16)

exp                               exponential function                               exp(16)

!                                   factorial                                                5!

Choose                          x choose y calculates the number 

                                    of ways of choosing a set of y elements 

                                    from a set of x distinct elements               5 choose 3

Constant              Meaning                                           Type into Search box

e                         base of the natural system of logarithms        e

pi                        the ratio of the circumference to 

                           the diameter of a circle                               pi/6

i                          imaginary number, which represents 

                           one of the two square roots of -1                  i^2

gamma                 Euler’s constant                                           e^gamma

Parenthesis can be used whenever they’ll serve to make complicated expressions unambiguous, and also sets of parenthesis can be used within parenthesis. Don’t use brackets for grouping.

You can force the calculator to try to evaluate expression by putting an equals sign (=) after it. This works only if the expression is arithmetically computable. For example, 1-800-555-1234= will return a result, but 1/0= will not (because dividing a non-zero number by zero is undefined and not computable).

Parenthesis can be used to enclose the parts of your expression that you want evaluated first. For example, (1+2)*3 causes the addition to happen before the multiplication.
