Teach Engineering: Trigonometry via Mobile Device

This trigonometry textbook takes the learner from a basic understanding of angles and triangles through the use of polar coordinates on the complex plane. Written by a mathematician-engineer, examples and problems here are used to...

Hold a free-throw shooting challenge in your engineering class! Each team must design a contraption that will fire off a "robot arm" or, more specifically, a catapult, to send a Ping-Pong ball into a basket. Use this as an opportunity to...

Geometry gets an engineering treatment in an exercise involving a belt wrapped around two wheels of different dimensions. Along with the wheels, this belt problem connects concepts of right triangles, tangent lines, arc length, and...

In addition to understanding the concept of similar right triangles and how they apply to trigonometric ratios, students explore a clinometer app, and discover how it can be used to test the mathematics underpinning trigonometry.

Students groups act as aerospace engineering teams competing to create linear equations to guide space shuttles safely through obstacles generated by a modeling game in level-based rounds. Each round provides a different configuration of...

For this online math worksheet, students practice using their calculator to perform trigonomic functions. This excellent resource allows the students to check their answers, and to get "hints" should they run into difficulties. A...

Some things are hard to resist. Small collaborative groups build circuits and calculate the voltage using Ohm's Law. Budding engineers explore the connection between the voltage across different resistors and linear...

Complex doesn't have to mean harder! Learners experiment with online software to determine the quadratic equations with complex solutions. They use the quadratic formula to solve equations with both real and complex solutions.

High schoolers study the architectural designs of different popular sites. For this math lesson, students draw a grid diagram. They explain what geodesic algorithms are used for.

In this online electricity worksheet, students are asked 10 questions about electric current and battery energy, an online answer key provided.
