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.

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

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.

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

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

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

In this interactive object, learners identify charges on ions, write new formulas based on charge, and balance equations using coefficients.

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

Learners read an explanation of the RL time constant and examine the formula for calculating the instantaneous current value. The current is graphed as it climbs to maximum or drops to zero. Note* In the formulas in this module, the Greek letter epsilon should be the mathematical constant 'e'.

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.

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.

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