When you try to generate a plot of a constant function as in y = 5, LiveMath may not know what the dependencies are and may default to making y the independent variable. If it does this, LiveMath will not be able to draw the graph and will give an error message.
If the Graph Variables dependency box opens, make sure you select x as the independent variable and y the dependent variable.
3.2 Constant multiplied onto a variable
Try not to confuse the concept of the derivative of a constant with the derivative of a constant times a variable. If a constant is all by itself, its derivative is zero. If it is multiplied onto a variable, it multiplies onto the derivative of the variable. After you study the Product Rule, come back and solve this problem again using that new rule.
Implicit graphs do not guess the viewing domain and range as well as other kinds of graphs, requiring you to adjust the viewing window with the zoom features along side the Graph Theory. In this example you may need to zoom out a couple of times. Also, in many implicit plots, you may need to increase the resolution by clicking on the mesh icon.
