Plottron vs GraphCalcPro2Go

A graphing + scientific calculator. • 2D and 3D graphing Graphs regular functions, parametric relations, and functions in polar/spherical coordinates. • Implicit graphing • Visualization of complex maps w=f(z) featuring domain coloring plots • For 2D functions: Info mode with tangent line and 2nd-order Taylor approximation Scientific calculator features: • User-defined variables and functions • Symbolic derivative (e.g.: D(x, sin(x)) • nCr, nPr, factorial • Complex numbers • Live evaluation (calculate as you type) • Calculation history • Probability density functions: Binomial, Normal (Gaussian), Student’s t • Cumulative probability density functions • Inverse CDF functions: Normal (Gaussian), Student’s t Examples: Implicit graph: cos(X)=sin(Y) Graph a parabola in Regular mode: X^2 Graph a circle in Parametric mode: cos(T);sin(T) Set a variable: X=5 Use a variable: X+4: 9 Define a function: f(X)=X+1 Use a defined function: f(2): 3 Symbolic derivative: D(X,sin(X)): cos(X) Complex magnitude plot in 3D Regular mode: abs(1/cos(X+Yi)) Notes: • Swipe left for settings. • Use semicolon (;) to separate functions in parametric relations. • Swipe down on keypad to show full history. Tap on answer to show keypad again.

GraphCalcPro2Go is an advanced scientific calculator, offering features found on expensive handheld calculators, but with additional capabilities not possible with handhelds, thanks to iOS. Features include: • No ads. Ever. • Ultra high precision and range • Intuitive and easy to use • Standard (in-fix) and RPN modes • Built-in constants and unit conversions • iCloud sync With iCloud sync, you can synchronize your calculation history with GraphCalcPro2Go on all your iOS devices, and with GraphCalcPro on your Macs. Sharing feature allows you to share your calculation history with other users running GraphCalcPro2Go on their iOS devices and GraphCalcPro on their Macs. Additionally, you can create beautiful graphs with GCP2Go at the touch of a button. And now, you can run GCP2Go on your Apple Watch. GCP2Go on Apple Watch has the precision, performance, and all the scientific functions available on the iOS version - and graphing capability! Sync constants, and optionally history, between GCP2Go on your iPhone and your Apple Watch. Premium upgrade adds additional features, including: • Graph multiple equations simultaneously • Graph printing and sharing • Additional built-in constants, fully customizable • iCloud sync and sharing of user constants
