Now, we are ready to solve the equation. First, we need to put the two

equations together into a vector. We can do this by actually storing the

vector into a variable that we will call EQS (EQuationS):

As initial values for the variables y and Q we will use y = 5 (equal to the

, which is the maximum value that y can take) and Q = 10 (this is

a guess). To obtain the solution we select function MSLV from the NUM.SLV

menu, e.g., ‚Ï6@@@OK@@@, to place the command in the screen:

Next, we’ll enter variable EQS: LL@@EQS@ , followed by vector [y,Q]:

‚í„Ô~„y‚í~q™

and by the initial guesses ‚í„Ô5‚í 10.

Before pressing `, the screen will look like this:

Press ` to solve the system of equations. You may, if your angular

measure is not set to radians, get the following request:
