General Tips

• Graphical Processor

GraphCalcPro is an advanced scientific calculator, offering features found on expensive handheld calculators, as well as additional capabilities not possible with handhelds. Features include. Ultra high precision and range. Intuitive and easy to use. Standard (in-fix) and RPN modes.

• Numbers can be entered by clicking on number buttons, or using the keyboard or keypad.
• Numbers can be copied from and pasted into the display by clicking on the display to select it, and using the 'Copy' and 'Paste' menu items under the 'Edit' menu.
• For unary functions, such as x², eˣ, sin, log, first enter the operand (number, constant, or the variable 'x'), then click the function button.
• Some operators can be invoked using hot keys on the keyboard and keypad:

• . Ghost Browser. GiD. Gideros. Gifox. Gifski. GiftList. Gin Rummy. Gin Rummy Ultra. Gisto. GitFinder. GitHub Classroom Assistant. GitHub Desktop. GitKraken. GitPigeon. GitUp. Gitify. Gladys. Glass Viper. GlassFish. Glimpses. GlitchUp. Glnemo2. Global protect. Globe Geography.
• Good Grapher (formerly known as GraphCalcPro) iOS, OS X: free Pro version available: solving quadratic equations; solving system of equations; can replace the TI83 for most high school graphing problems. Points of intersections; roots; intercepts.

• Backspace button: Deletes the last entered digit during number entry. If not actively entering a number, the backspace button steps backward in the calculation, deleting the last entered number or operation. Control-click erases the current calculation.
• Constant button: Enters the currently displayed constant. Control-click this button to reveal and select other constants. To edit the constants or add your own, go to the 'Constants' tab under Preferences.
• Variable button: Enters the 'x' variable for equations, similar to entering a constant or number. For example, to enter the equation '3 + sin(x) =', click the buttons '3' '+' 'x' 'sin' '=' in that order. To enter 'x² =', click the buttons 'x' 'x²' '='.
• Set Variable Value button: Allows entry of a value for the variable. After entering a complete equation (including =), you can enter a number and click this button to set the value of x, and the result of the equation will be calculated. For example, after entering the equation 'x² =', enter 4 and click →x , and 16 will be displayed. Enter 8 and click →x, and 64 will be displayed. This is convenient to quickly calculate the value of an equation for multiple different variable values.
• Graph button: Graphs the currently entered equation. Control-click this button to graph multiple equations simultaneously.
• Unit Conversion buttons (℉→℃, in→cm, lb→kg): Control-click to reveal and select other conversions. The 2ᴺᴰ button inverts the currently displayed conversions.

Graphing

Single equation: Enter an equation, and click the Graph button.

Multiple equations: GraphCalcPro keeps a list of the last 4 graphed equations. To access the list, control-click on the Graph button. Each graphed equation is added to the top of the list. For example, enter sin(x) =, and click the Graph button. Close the graph. Next enter cos(x) =, and control-click the Graph button. A pop-up will be displayed with the list of the equations. The list can be rearranged and edited. Clicking the 'Graph' button in this pop-up, and GraphCalcPro will graph the equations in the list simultaneously, autoscaling to the first equation in the list.

Customization: Graph colors and line thickness can be changed from Preferences, under the 'Graph' tab.
