The most accurate graphing calculator for Android. Cartesian and polar graphs, table of values, complex numbers, differentiation, integration, area, arc length, an easy-to-use units converter and choice of background color. • Graph functions on an interval.Example: f(x) = xsin(2x) intvl=(-2, ∞).• Graph functions, f(θ), using polar coordinate system too.Example: f(θ) = 3sin(2θ) intvl=(0, 2π).• This graphing calculator is generally able to identify 'holes' in the graph of a function and also draw the asymptotes separate from the graph with dashed lines.• Calculate complex numbers expressions. Example: (2+3i)^i+5∠ (4). You can use i or j for the imaginary unit.• Generate table of values for functions. • Calculate definite integral, area and arc length. • Degrees and Radians mode.• Units Converter - convert units of length, mass, time,... . In addition, the followings are available periodically or when you upgrade• Graph parametric equations on an interval. Example: p(t) = 3cos(3t), 3sin(2t) intvl=(0, 2π). Note: enter x(t) and y(t) separated by a comma (no enclosing parentheses around p(t) ).• Graph point sets and fit a curve by a polynomial (interpolating) of the least degree that contains the given points; find and graph the line (least-squares line) that best fits the given points. Example (Points): 1,2; 2,3; 4,5; Note: enter the point (x,y) as x,y;• Graph parametric equations (θ(t), r(t)) and point sets (θ, r) using polar coordinate system too.Example: p(t) = 3cos(3t), 3sin(2t) intvl=(0, 2π). Note: enter θ(t) and r(t) separated by a comma as above -- the first component is θ(t) -- (no enclosing parentheses around p(t)).Example (Points): 1,2; π,3; π/2,5; Note: The first component is θ; enter the point (θ,r) as θ,r;• Calculate derivatives (symbolic) of functions and parametric curves and graph them. • Solve f(x)= 0 to find all the x-intercepts (zeros or roots of a function) on an interval without guesswork. • Scientific, engineering and fixed point notations.You can use the following in your expressions• Basic algebraic operations • Trigonometric functions and their inverses (RAD and DEG)• Hyperbolic functions and their inverses • Exponential and logarithmic functions• Absolute value and step functions.If your expression is incomplete or if you make a syntax error the = sign changes to ? mark. When you touch it, this artificial intelligent graphing calculator gives you a feedback by precisely indicating the error. When no interval is specified, the graphing calculator automatically appends a default interval to the function or and parametric expression and draws the graph on that interval. You can change the endpoints of the interval, of course. This convenient feature is unique to the gCalcD graphing calculator. Touch Polar on the upper right of the graphing area to draw the graphs using the polar coordinate system.Touch and drag the graphs to see the required region. To center the graph on the screen, touch the coordinate indicator on the top left of the graphing area.Touch ++ or -- on the lower right corner of the graphing area to zoom in or zoom out. Touch the lower left corner of the graphing area (where the caption is) to reset zoom.On this graphing calculate most keys are assigned a second functionality by long pressing. For example* Long press of the back-space button x←: Clears the input box. Immediately after pressing it will display back the deleted expression. * Long press of ^ (power) sign: Appends the 'intvl=(' to the expression if it is not already appended or deleted. Long press of decimal point inserts comma to separate the end-points.All of the above with more details are included in the built-in help menu of the calculator.
