One equation
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 = U 2 +2AD.
where V = final speed, U = initial speed, A = acceleration
needed, and D = distance.
Open the
Solve app
1. Open the Solve app.
I Select Solve
The Solve app starts in
Symbolic view, where you
specify the equation to
solve.
N O T E 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 = G 2 + ME.
Functions defined in other apps can also be referenced in the
Solve app. For example, if you have defined F1(X) to be X
2 +10
in the Function app, you can enter F1(X)=50 in the Solve app
to solve the equation X 2 + 10 = 50.
