图形计算器Graphing Calcu... 描述

With the most graphing features on Google Play, this integrated scientific/graphing calculator is exceptionally easy to use. You don't have to switch between scientific and graphing modes or switch from different types of graphs. It also has the capability to calculate complex numbers in any form and show the result in all different forms. Whether it's a fiction, parametric equation or a set of points through which you want to find and pass a polynomial function, this powerful graphing calculator automatically detects the type of expressions, and if necessary, for convenience, appends a default interval to function and parametric expressions and graphs on that interval using Cartesian or polar coordinate systems. You can change the endpoints of the interval. Examples:
Function: f(x) = xsin(2x) intvl=(-∞, ∞). (You don't have to type in the interval 'intvl=(-∞, ∞)'; the graphing calculator appends it when you press the graph button. You can change the end-points as desired.)
When you select the polar coordinate system, the graphing calculator automatically replaces all x's with θ's and graphs on the default interval (0, 2π) if no other interval is specified..
Parametric: p(t) = 3cos(3t), 3sin(2t) intvl=(0, 2π). Note: enter x(t) and y(t) separated by a comma -- no enclosing parentheses around x(t), y(t) .
Point set : 1,2; 2,3; π/2,(2+3)/2; Note: enter the point (x,y) as x,y; -- also note that you can use numeric expressions for the coordinates. The graphing calculator gives you the equation of the polynomial passing through the points and graphs the polynomial. Optionally, the calculator computes and graphs the linear regression line.
Graph using polar coordinate system too.
Generate table of values for functions f(x) and parametric equations p(t).
Choice of scientific, engineering and fixed point notations.
Calculate expressions containing complex numbers, such as, (1+2i)^i-3∠(π/4) with this integrated scientific / graphing calculator. The result is given in standard, polar and other forms.
Choice of background color for the calculator.
Easy to use units converter. (Time, Mass, Length, Velocity, and many more.)
You can use the following in your expressions
Basic algebraic operations
Power functions, x^r and E(x)
Trigonometric functions and their inverses (RAD, DEG)
Hyperbolic functions and their inverses
Exponential , e^x and exp(x), and logarithmic functions
Factorial, the Gamma function Γ and Psi function Ψ
Absolute value and step functions, round, floor, ceil.
If your expression is incomplete or if you make a syntax error touch the ? mark; this intelligent graphing calculator gives you feedback by precisely indicating the error
The calculator also provides a very useful and intuitive units converter for converting units of mass, length, time and many more quantities.
When viewing the Graphs:
Touch Polar on the upper right corner of the graphing area to draw the graphs in polar coordinate system.
Touch ++ or -- on the lower right corner of the graphing area to zoom in or out.
Drag the graphs. To center the graph on the screen, touch the coordinate indicator on the top left corner of the graphing area.
Touch the lower left corner of the graphing area (where the caption is) to reset zoom.
Calculate all the x-intercepts of the graph of a function on an interval with a single click.
Calculate the points of intersection of the graphs of two functions.
Calculate symbolic derivatives of functions and parametric equations and graph them.
Generate table of values for functions and parametric equations.
Calculate definite integral, area under (or enclosed by) the graphs of functions (or parametric curves) and arc length in both Cartesian and polar cases.
All of the above with more details are included in the built-in Instruction menu accompanying this graphing calculator.

函数：F（X）= xsin（2×）INTVL =（ - ＆＃8734;，＆＃8734）。 （您不必键入在区间'INTVL =（ - ＆＃8734;，＆＃8734;）';当你按下按钮图形的图形计算器追加它可以根据需要更改结束点。 ）
