Editor’s Note: This DI is a two-part series. Part 1 shows how to make an oscillator with a pitch that is proportional to a control voltage. Part 2 shows how to modify the circuit for use with higher ...
Most linear algebra courses start by considering how to solve a system of linear equations. \[ \begin{align} a_{0,0}x_0 + a_{0,1}x_0 + \cdots a_{0,n-1}x_0 & = b_0 ...
Required study by high schools and colleges, algebra has been a notorious stumbling block for students. Without a solid foundation in algebra, however, you cannot expect to do well in more advanced ...
