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.

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

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 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.

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.

In this animated object, learners examine formulas for displacement and velocity ratios. They also view examples and calculate velocity and the velocity ratio.

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

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

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

The current-to-voltage conversion of the transresistance amplifier is examined. The formulas for output voltage and impedance are defined and an example ties the concepts together.

The ohmic region of the E-MOSFET is identified. Formulas are given to determine the proper operation in the ohmic region. An example of circuit analysis is also given.

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.

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

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.
