Formulas and Functions in Microsoft Excel

A learning object to illustrate the right way to enter formulas and functions in Excel.

In this learning activity you'll create strategies for sending and receiving complaints and requests.

Students read an explanation of chemical formulas in this animated activity. A quiz completes the object.

Use Ohm's law, Watt's law, and the power equation to derive formulas for the DC power wheel.

In this interactive object, learners complete dental formulas for various species of animals.

In this module we will explore some commonly used formulas for area and volume.

Learners follow a four-step process to determine the empirical formula of a compound from the masses of its constituent elements. The molecular formula is determined in a fifth step using the molecular weight of the compound.

In this learning activity you'll identify abbreviations that represent quantities associated with electrical circuits.

Students read an explanation of the summing amplifier and the formulas for closed-loop gain. An example is given.

Learners examine the formulas that are used to determine the proper PID values to be entered into a controller using the Ziegler-Nichols Continuous Cycling Tuning Method.

Students examine the drain curves for a JFET. They are also introduced to vocabulary terms and formulas.

Learners study the properties of a rectangular solid and use geometric formulas to find volume and surface area.

Learners study the properties of a sphere and use geometric formulas to find volume and surface area.

Students read how to calculate the size of a hydraulic cylinder that is required for a particular application. Mathematical formulas are provided.

Students are introduced to the non-inverting amplifier configuration. The formulas for closed loop gain and bandwidth are shown, and an example is given.

Learners review the three formulas for power and work 12 problems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and asked to solve for power. Immediate feedback is provided.

In this animated and interactive object, learners examine the definitions and formulas for radius, diameter, circumference, and area. Students also solve practice problems involving the circumference and area of a circle.

Students view the formulas to be used to convert a series impedance to a parallel impedance.

In this animated object, learners examine the operation of a summing operational amplifier through formulas, tables, and animated illustrations. A brief quiz completes the activity.

The learner will apply the three formulas used to find the total resistance of three types of parallel resistor circuit configurations.
