Plot the equation

The Plot view shows one graph for each side of the solved equation. You can choose any of the variables to be the independent variable by selecting it in Numeric view. So in this example make sure that A is highlighted.

The current equation is V 2 = U2 +2AD. The plot view will plot two equations, one for each side of the equation. One of these is Y = V 2, with V = 27.78, making Y = 771.7284. This graph will be a horizontal line. The other graph will be Y = U2 +2AD with U =16.67and D =100, making, Y = 200A + 277.8889. This graph is also a line. The desired solution is the value of A where these two lines intersect.

(where n is the number of the selected equation)

8.By default, the tracer is active. Using the cursor keys, move the trace cursor along either graph until it nears the intersection.Note that the value of A displayed near the bottom left corner of the screen closely

matches the value of A you calculated above.

The Plot view provides a convenient way to find an approximation to a solution when you suspect that there are a number of solutions. Move the trace cursor close to the solution (that is, the intersection) of interest to you and then open Numeric view. The solution given in Numeric view will be will be for the solution nearest the trace cursor.
