### Javascript Magic

Use your Internet Explorer Browser as a Calculator!

Type this single line into the "Address" (URL) textarea

of your IE Browser and press Enter.

javascript:7+4

and you should get the answer 11 on the window page.

Now do the same for -

javascript:alert(8-5)

and you should get the answer 3 in an alert box.

Now try these -

javascript:'Math Class'

javascript:alert('This is Math Class')

javascript:Date()

javascript:alert(Date())

Again, Type the following single line Math expression into the

"Address" (URL) textarea of your IE Browser and press Enter.

javascript:Math.cos(1.5)

Now do the same for -

javascript:alert(Math.PI)

Also, type these inside the above two examples -

Math.abs(number) ....absolute value

Math.acos(number) ....arc cosine (in radians)

Math.asin(number) ....arc sine (in radians)

Math.atan(number) ....arc tangent (in radians)

Math.cos(num_radians) ....cosine

Math.sin(num_radians) ....sine

Math.tan(num_radians) ....tangent

Math.ceil(number) ....smallest integer >= number

Math.floor(number) ....largest integer <= number

Math.exp(number) ....e to the power of number

Math.log(number) ....natural log of number

Math.pow(base,exponent) ....base to exponent power

Math.max(number,number) ....greater of the two numbers

Math.min(number,number) ....smaller of the two numbers

Math.round(number) ....rounds the number to the nearest integer

Math.sqrt(number) ....finds the square root of the number

Math.PI .... pi (3.14159...)

Math.E ....e (2.718...)

Math.LN2 ....natural log of 2 (0.693...)

Math.LN10() ....natural log of 10 (2.302...)

Math.LOG10E() ....base 10 log of e (0.434...)

Math.SQRT1_2() ....square root of 1/2 (0.707...)

Math.SQRT2 ....square root of 2 (1.414...)
