HP50g – Lesson 20:
Finding Slope, Area, Derivatives while in Graph Mode

In this section, the student will be taught how to use the built in functions
that are available while in graph mode to find the slope of a point on a curve,
the area under the curve, the derivative, and more.

Circuit Analysis: Volume 1 – Section 6
Kirchhoff’s Voltage Law

In this lesson, we introduce the concept known as Kirchhoff’s Voltage
Law (KVL), which is the companion law to the Current Law that we
discussed in the previous section. Here, we learn how to walk around
any loop of a circuit and write an equation that relates the voltage drop
across all circuit elements. Using Kirchhoff’s Voltage Law along with
the KCL law learned previously allows us to solve circuits of increasing
complexity.

Circuit Analysis, Volume 1 – Lesson 5
Kirchhoff’s Current Law

In this lesson, we introduce the very important concept known as
Kirchhoff’s Law (KCL). We will use this law repeatedly as we solve
circuits because it is a universal relation that holds for all nodes in a
circuit. After viewing this lesson, the student will be comfortable
writing KCL equations at the nodes of any circuit.

Circuit Analysis, Vol 1 – Lesson 4 –
Power Calculation in Electric Circuits

In this lesson, we discuss the topic of power calculations in electric
circuits. We begin by defining the unit of Power as being the Watt and
how this unit relates to energy flow in a circuit. We then explain the
sign convention for positive and negative power in circuit calculations.
Finally, we use the power formulas to calculation power absorbed and
delivered in circuits.

Hp 50g, Lesson 19 – Graphing Multiple Equations

In this section, the student will learn how to graph two equations on the same set
of coordinate axes, how to trace the graphs to get (x,y) information from the plots,
and how to find the intersections of the graphs.

Hp 50g Calculator – Graphing Single Equations

In this section, the we will learn how to graph equations in the HP50g graphing
calculator. The student is taught how to enter the equation to be graphed, set
the window zoom parameters, graph the function, and trace the results to get
the (x,y) points on the graph.

Chemistry 1, Volume 2
Percent Yield in Chemical Reactions

In this section, we explore the concept of the percent yield in
a chemical reaction. We define the concept and then work several
examples that show how the calculate the percent yield of a reaction.

Chemistry 1, Volume 2 – Section 11 –
Limiting Reactants – Part 2

In this section, we continue to work problems that require the use
of the concept of the limiting reactant in a chemical reaction.
