This calculator can be used to solve a single non-linear equation of the user’s choice. It requires entering the equation and a starting value. To illustrate consider the example equation from Chapter 7, f(x) = tan(x)* sin(x) – 2.15 = 0. Be sure you are in radian mode. Select 2nd num-solv (over sin key) Key in the equation: tan(x)* sin(x ...
SOLVING SYSTEMS USING MATRICES—THE LONG WAY AND …
Now let’s use a quick method for using matrices to solve systems. Recall that matrix A contains the coefficients of x and y and matrix B contains the constants. To do this, multiply the inverse of matrix A by matrix B. Enter the command [A]-1([B] and press (. The resulting matrix contains the solution.
