![]() E.g.x x^2 2Binary, octal, hexadecimal You can enter values in binary,octal orhexadecimal by prefixing them with 0b, 0o or 0xrespectivelly, suchas: binary: 0b1010 octal: 0o17 hex: 0x100įile Viewer for Android is a universal fileviewer that supports over 100 file types, including PDFs, emailfiles, audio and video files, images, camera raw photos, archives,and more. Multi plot To plot multiple functions on the same 2dgraph,simply enter them on the same line separated by " ". sqrt'(x).Tocompute the derivative of an expression you must definetheexpression as a named function: E.g. The prime mark (quote) must appearimmediatelyafter the name of the function, and must be followedbyopen-parentheses. Derivative It is possible to compute thefirstderivative of a function with one argument using theprimenotation: log'(5). Use trackball Up/Down tonavigatethe history. Angles in degrees instead of radians:useeither sind(90) or sin(90deg). ![]() Clear:use theEnter key to quickly erase the whole input line. Multiplication: you mayomitthe multiplication operator when unambiguous, e.g.3π+2(1+2)Expression continuation: starting a new expression with anoperatorauto-inserts ans, the result of the last expression. rnd(max): random value from [0, max).gamma(x): (x-1)!mod(x,y): modulo Complex numbers i or j is thecomplex base.Example: i*i (1+i)^2 e^(i*pi) Operators + - × ÷ basicarithmetic ^power % percent ! factorial # modulo √ square root 'firstderivative Tips Parentheses: you may omit the leading orfinalparentheses, e.g. Predefined functionsLogarithmsand power sqrt(x): square root x^0.5 cbrt(x): cube root x^(1/3)exp(x): exponential e^x log(x), ln(x): natural logarithmlog2(x),lb(x): binary logarithm log10(x), lg(x): decimallogarithmlog(base,x): arbitrary base logarithm Trigonometric -radianssin(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 divisorcomb(n,k): combinationsperm(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). Ittogglesopened/closed the letter keypad. Special mod for KI-14-1 :) Enjoy! Sampleexpressionssimple expression: 1+2 variable evaluation: pi functionevaluation:sin(0) variable definition: a=3.5 function definition:f(x)=x^2-1parentheses: (1-x)^2 To enter an expression cointainingletters,such as sin(x), use the ⇳ key on the basic keypad.
