<b>Some technical remarks:</b> This calculator works only in radians.
|
|
(Multiply angles by pi/180 to convert from degrees to radians.)
|
|
<br/>
|
|
|
|
The syntax is loosely based on JavaScript and a subset of ASCIIMathML.
|
|
<br/>
|
|
The multiplication symbol * can be omitted after a digit (0-9)
|
|
or a closing parenthesis.
|
|
<br/>
|
|
Available constants and functions:
|
|
<br/>
|
|
+, -, *, /, ^, pi, e, sqrt(), ln(), abs(), sign(),
|
|
floor(), ceil(), n!, C(n,k), ran(a,b,n)
|
|
<br/>
|
|
sin(), cos(), tan(), sin^-1(), cos^-1(), tan^-1(),
|
|
sinh(), cosh(), tanh(), sinh^-1(), cosh^-1(), tanh^-1()
|
|
<br/>
|
|
sec(), csc(), cot(), sec^-1(), csc^-1(), cot^-1(),
|
|
sech(), csch(), coth(), sech^-1(), csch^-1(), coth^-1()
|
|
|
|
<br/>
|
|
Values can be assigned to (legal JavaScript) variable names.
|
|
Use ";" to separate expressions.
|
|
<br/>
|
|
Any number of calculator textareas can be placed anywhere on <b>your own</b>
|
|
webpages.
