# Insert an equation Choose in the main menu to plot a new equation You'll see the default equation x is loaded   Choose the Insert command (on most devices this is the fire button or pressing the joystick) You'll see the different functions that can be inserted Scroll up (or downwards) untill sin(x) is shown Choose the Insert command The function will be inserted   Choose Plot, if you want to view the Graph

# Plot a sample equation Go to the main menu and select the Samples item Choose the sample you like to plot (e.g. Climbing sine) You'll see the equations of the sample Open the Options menu (On most devices this can be done by the left selection key)   Choose Plot, if you want to view the Graph You'll see the sample right now   You can zoom in (5) out (0), move (arrows), evaluate the function (left selection key -> "Evaluate function") or show the function table (left selection key -> "Show Table")

# Save an equation Go to the Graph Options of the equations you want to save. Open the Options menu (On most devices this can be done by the left selection key)   Choose the "Save as Sample" option You can enter the name of the new sample (e.g. my equations) and choose OK You'll see a message when your sample is succesfully saved When you open the Samples-menu, you'll see your own added sample   Next time you start GraphViewer, your sample will still be there (even sorted alphabetically) in the sample-menu

# Calculate the derivate in a point of the function Start the Calculator from the main menu Enter the equation inside D( ) (E.g. D(x^2) to calculate the derivate in any point of x^2)   Select the appropriate X Value, where you want to calculate the derivate (E.g. 3)   When you hit the Calculate button, the derivate will be calculated in the chosen point.

# Calculate a definite integral Start the Calculator from the main menu Insert the integral you want to calculate in the form I(x1, x2, f): this will calculate the definite integral between x1 and x2 of function f (e.g. I(2,4,x) will calculate the area under the graph f(x)=x for x between 2 and 4. or more formaly, this will calculate: # Use a white background    Open the Settings from the main menu Unmark the Black Background option   Choose OK from the Options menu (or hit the OK button) GraphViewer Home Designed by Tim Vermeiren (2016) Translated by Tim Vermeiren
