Graph Calc Plus vs Replay FX GOLD

Graph Calculator define the graph of [f] to be the graph of the equation y = f(x). So, the graph of a function if a special case of the graph of an equation. Features: ∙ Set individual line color. ∙ Show/Hide individual mathematical expression. ∙ Pinch to Zoom in/out Graph View. ∙ Pan to reposition Graph View. ∙ Add up to 22 mathematical expressions. ∙ Full screen preview. Graph Features: ∙ Custom background color for Graph. ∙ Custom grid color for Graph. ∙ Show/Hide Grid Lines/Minor Grid Lines. ∙ Show/Hide Axis Number. ∙ Show/Hide X-Axis. ∙ Show/Hide Y-Axis. ∙ Set Graph Line Width range from 0.5~5.0. Some of the most commonly used functions: y = mx + b y = x**2 [x²] y = x**3 [x³] y = sqrt(x) [√x] y = ln(x) y = log(x) y = sin(x) y = cos(x) y = tan(x) Standard Operators: + - addition and unary positive - - subtraction and negation * - multiplication / - division ! - factorial ** - pow, exponentiation sqrt(x) - square root cuberoot(x) - cubic root Standard parameters (constant): phi - returns the value of ϕ (the Golden Ratio). Also recognized as ϕ() pi - returns the value of π. Also recognized as π() pi_2 - returns the value of π/2 pi_4 - returns the value of π/4 tau - returns the value of τ. Also recognized as τ() sqrt2 - returns the value of the square root of 2 e - returns the value of e log2e - returns the value of the log base 2 of e log10e - returns the value of the log base 10 of e ln2 - returns the value of the log base e of 2 ln10 - returns the value of the log base e of 10 Standard Functions that take 1 parameter: sqrt() - returns the square root of the passed parameter log() - returns the base 10 log of the passed parameter ln() - returns the base e log of the passed parameter log2() - returns the base 2 log of the passed parameter ceil() - returns the passed parameter rounded up floor() - returns the passed parameter rounded down Trigonometric functions: sin(), cos(), tan() Their inverses (asin, acos, atan, atan2) Their reciprocals (csc, sec, cotan) The reciprocals of the inverses (acsc, asec, acotan) The hyperbolic variations of all the above functions (sinh, cosh, tanh, asinh, acosh, atanh, csch, sech, cotanh, acsch, asech, acotanh) The versine functions (versin, vercosin, coversin, covercosin, haversin, havercosin, hacoversin, hacovercosin, exsec, excsc, crd) dtor() - converts the passed parameter from degrees to radians rtod() - converts the passed parameter from radians to degrees Quick Start: 1. Tap on [+] button. 2. Change the equation of the line to y=3x+1 and see graphed. 3. You can also enter equations that are not solved for x e.g. x=2y+2 About Graph Calculator In mathematics, the graph of a function f is the set of ordered pairs (x,y), where f(x)=y. In the common case where x and f(x) are real numbers, these pairs are Cartesian coordinates of points in two-dimensional space and thus form a subset of this plane.
