Although no charge or fee is required for using TeachEngineering curricular materials in your classroom, the lessons and activities often require material supplies.
The expendable cost is the estimated cost of supplies needed for each group of students involved in the activity. Most curricular materials in TeachEngineering are hierarchically organized; i.
Some activities or lessons, however, were developed to stand alone, and hence, they might not conform to this strict hierarchy. Related Curriculum shows how the document you are currently viewing fits into this hierarchy of curricular materials. How wide is a river? Sometimes engineers cannot directly measure an object's size or distance because it would take too much time, or it is physically impossible a tape measure to find the distance from the Earth to Pluto?
Instead of actually measuring a size or distance, engineers use trigonometry and other mathematical relationships to estimate it very accurately. Each TeachEngineering lesson or activity is correlated to one or more K science, technology, engineering or math STEM educational standards. In the ASN, standards are hierarchically structured: first by source; e. View aligned curriculum. Do you agree with this alignment?
Thanks for your feedback! Students explore the concept of similar right triangles and how they apply to trigonometric ratios. Use this lesson as a refresher of what trig ratios are and how they work. First they review fundamental geometrical and trigonometric concepts.
Then, they estimate the height of various objects by using simple trigonometry. Students learn that math is important in navigation and engineering. They use the Pythagorean Theorem to solve real-world problems. High school students learn how engineers mathematically design roller coaster paths using the approach that a curved path can be approximated by a sequence of many short inclines.
They apply basic calculus and the work-energy theorem for non-conservative forces to quantify the friction along a curve Is it possible to determine the width of a river without crossing it? Answer: It is possible to come very close to determining the width of a river of any size, using triangles. The same principle used to determine the width of a river can be applied to other situations, including determining the height of a hill, a tree or a building.
The simple geometric shape that makes this all possible is the triangle. During this activity, you will learn how to use triangles to determine the width of a river. Trigonometry is a branch of mathematics dealing with relationships between the angles and sides of triangles.
The three basic trigonometric relations that we are concerned with in this activity are: sine, cosine, and tangent abbreviated as sin, cos, and tan. They are the ratios of the lengths of two sides of a particular triangle.Explore the surplus collection of trigonometry worksheets that cover key skills in quadrants and angles, measuring angles in degrees and radians, conversion between degrees, minutes and radians, understanding the six trigonometric ratios, unit circles, frequently used trigonometric identities, evaluating, proving and verifying trigonometric expressions and the list go on Grasp and retain trigonometric concepts with ease employing these visually appealing charts for quadrants and angles, right triangle trigonometric ratio chart, trigonometric ratio tables, allied angles and unit circle charts to mention a few.

This puzzle activity is a fun way for students to practice their understanding and interpretation of Sine and Cosine graphs.I selected this problem so that we can review again how to either factor a trig equation or apply the quadratic formula.
I ask that if students get stuck, they text me their last step. Up to this point, my students have been successful in applying the quadratic formula to a quadratic trig equation. However, they were confused about how to interpret their solutions. After students complete the warm-up, I will model both methods.
First, how to factor this polynomial to get solutions. The results in this problem present a good opportunity to also discuss why this equation would not produce any solutions.
I like the idea of a puzzle instead of just a worksheet because it builds in an opportunity for review and self-assessment. Do the pieces go together and all match? Then they are right! I think that the visual nature of the puzzle helps kids to recognize patterns and reason about mistakes by considering alternatives.
