HP50g Tutor, Volume 1 – Sect 22
The Complex Number Menu
In this lesson, you will learn how to manipulate and perform more
computations that involve complex numbers. Specifically, the student
will learn how to calculate the absolute value, real part, imaginary
part, conjugate, and more!
Engineering Circuit Analysis: Vol 1 – Section 1
Introduction to the Node Voltage Method
In this lesson, we begin to study a more advanced solution method
for circuits known as the Node Voltage Method. This method is ultimately
easier to solve for most circuits because it requires less equations to be written.
We explain the technique and provide a step-by-step example to give the
student a solid foundation. Subsequent sections will solve problems of
increasing complexity with the Node Voltage method.
HP50g – Lesson 21 – Working with Complex Numbers
In this section, you will learn how to enter and perform computations that
involve complex numbers. Complex numbers are numbers that have a real
and imaginary part and are used in every branch of math, science, and
engineering. We’ll learn how to enter complex numbers in rectangular form
and polar form, learn how to convert between these forms, and how to
perform math operations.
In this science video, you’ll learn how to build a simple battery out of a lemon
and other household materials! We’ll use this battery to power an electronic
calculator!
