Suppose you want to find the acceleration needed to increase the speed of a car from 16.67 m/s (60 kph) to 27.78 m/s (100 kph) over a distance of 100 m.

The equation to solve is:

V 2 = U2 +2AD.

where V = final speed, U = initial speed, A = acceleration needed, and D = distance.

1.Open the Solve app. ISelect Solve

The Solve app starts in Symbolic view, where you specify the equation to solve.

In addition to the built-in variables, you can use one or more variables you created yourself (either in Home view or in the CAS). For example, if you’ve created a variable called ME, you could include it in an equation such as this: Y 2 = G2 + ME.

Functions defined in other apps can also be referenced in the Solve app. For example, if you have defined F1(X) to be X2 +10 in the Function app, you can enter F1(X)=50 in the Solve app to solve the equation X2 + 10 = 50.

2.If you have no need for any equations or expressions already

defined, press SJ(Clear). Tap to confirm your intention to clear the app.

3.Define the equation.
