Calculator Details

basic calculator, scientific calculator and graphing calculator, it also allows you to DIY your own calculator. Sample expressions simple expression: 1+2 variable evaluation: pi function evaluation: sin(0) variable definition: a=3.5 function definition: f(x)=x^2-1 parentheses: (1-x)^2 You can call the function by simple input f(xxx), for example, if you define a function `f(x,x1) = x + x1`, and if you input `f(2,3)`, the result will be `5`. Predefined functions Logarithms and power sqrt(x): square root; x^0.5 curt(x): cube root; x^(1/3) log(x), ln(x): natural logarithm log10(x), lg(x): decimal logarithm log(base,x): arbitrary base logarithm Trigonometric - radians sin(x), cos(x), tan(x) asin(x), acos(x), atan(x) Trigonometric - degrees sind(x), cosd(x), tand(x) asind(x), acosd(x), atand(x) Hyperbolic sinh(x), cosh(x), tanh(x) asinh(x), acosh(x), atanh(x) Other gcd(x,y): greatest common divisor comb(n,k): combinations perm(n,k): permutations min(x,y), max(x,y) floor(x), ceil(x) abs(x): absolute value sign(x): signum rnd(): random value from [0,1). rnd(max): random value from [0, max). gamma(x): (x-1)! mod(x,y): modulo Complex numbers i or j is the complex base. Example: i*i (1+i)^2 e^(i*pi) Operators + - × ÷ basic arithmetic ^ power ! factorial # modulo √ square root ' first derivative Tips Parentheses: you may omit the leading or final parentheses, e.g. 1+2)(3+4 is valid. Multiplication: you may omit the multiplication operator when unambiguous, e.g. 3π+2(1+2) Expression continuation: starting a new expression with an operator auto-inserts ans, the result of the last expression. Clear: use the Enter key to quickly erase the whole input line. Scientific e notation: 1e3 is 1000. Angles in degrees instead of radians: use either sind(90) or sin(90deg). Use trackball Up/Down to navigate the history. Derivative It is possible to compute the first derivative of a function with one argument using the prime notation: log'(5). The prime mark (quote) must appear immediately after the name of the function, and must be followed by open-parentheses. The derivative may be plotted e.g. sqrt'(x). To compute the derivative of an expression you must define the expression as a named function: E.g. f(x)=x^3+x^2+1, followed by f'(x). Multi plot To plot multiple functions on the same 2d graph, simply enter them on the same line separated by ";". E.g. x;x^2;2 Binary, octal, hexadecimal You can enter values in binary, octal or hexadecimal by prefixing them with 0b, 0o or 0x respectively, such as: binary: 0b1010 octal: 0o17 hexa: 0x100 if you want to display the result in binary, octal, hexadecimal, click the menu `DEC` in the calculator.
