How To: Given a system of equations, solve with matrices using a calculator. Save the augmented matrix as a matrix variable [A],[B],[C],…[A],[B],[C],…. Use the ref( function in the calculator, calling up each matrix variable as needed....
There is one interesting characteristic that trigonometric equations have. And that is that they have an infinite number of solutions. You might think this sounds weird, especially since your calculator only returns one answer. Let's look at the graph of the sine function and you will see somet...
