In this learning activity you'll evaluate the six trig functions using a scientific calculator.

Formulas and Functions in Microsoft Excel

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

In this animated object, learners examine the switch settings for the on-delay, off-delay, and one-shot timing functions of an optical sensor. A brief quiz completes the activity.

Learners observe the four functions of oil in a hydraulic system.

In this learning activity you'll practice calculating an inverse variation problem.

This screencast will help the student identify normal blood cells and their functions. This will include the identification of red blood cells, five types of white blood cells, and platelets.

The target audience of this learning object is trigonometry students who have already learned what a radian is and have already derived the key values of the coordinates associated with common radian units, but now need to practice finding those values on the unit circle. The student does not need to know the definition of the six trig functions to do this activity.

In this interactive object, students use the Law of Sines to calculate forces.

In this interactive object, learners use the Pythagorean Theorem to calculate forces.

In this interactive object, learners use the Law of Cosines to calculate forces.

In this animated object, learners examine the operation of a Schmitt Trigger IC and its hysteresis function. A brief quiz completes the activity.

Learners read how the transfer function for a RL high pass filter is developed. The transfer function is used in Excel to graph the Vout. The circuit is also simulated in Electronic WorkBench, and the resulting Bode plot is compared to the graph from Excel.

Students read how the transfer function for a RC low pass filter is developed. The transfer function is used in Excel to graph the Vout. The circuit is also simulated in Electronic WorkBench and the resulting Bode plot is compared to the graph from Excel.

Learners examine how to solve problems using the Pythagorean Theorem in Excel. Practice problems are included.

After a brief review, the student solves five practical shop problems using right angle trigonometry.

Learners read how the transfer function for a RC high pass filter is developed. The transfer function is used in Excel to graph the Vout. The circuit is also simulated in Electronic WorkBench and the resulting Bode plot is compared to the graph from Excel.

In this animated and interactive object, the learner uses a TI-36X calculator to solve for the magnitude of the resultant and of one of the component forces in a right triangle.

Learners read how the transfer function for a RC low pass filter is developed. The transfer function is used in Excel to graph the Vout. The circuit is also simulated in Electronic WorkBench and the resulting Bode plot is compared to the graph from Excel.

Students read about the ENTRY, INS, and DEL keys and view a demonstration of how to edit and insert characters and recall previous entries.

Learners apply the Law of Cosines to determine forces using a TI-36X calculator in this animated object.
