-1-1Key Radian Values on the Unit Circle
https://www.merlot.org/merlot/viewMaterial.htm?id=247543
This program provides practice thinking in terms of radian measure. Students can click on wedges of size pi/6, pi/4, pi/3, or pi/2 to move around the unit circle and land on the key values that all trig students need to learn. This program is appropriate for students who already know what a radian is, but need some practice working with radians. Students also should have already learned the key value on the unit circle, but they can practice locating where those values are at with this program. Students do not need to know the definition of the six trig functions to work with this program, but if your students already know those definitions, you can easily add some questions about the trig functions as they are working with the program.<br /><br />trig, unit circle, radian measure, math, precalculus, trigonometrySun, 25 Mar 2007 05:33:29 GMTLaura Shears Lansing Community CollegeVector Drawing Board
https://www.merlot.org/merlot/viewMaterial.htm?id=247557
A place to draw vectors and break them up into their components, move them, negate them, add them, etc. Good program to project onto a white board for an in class discussion or to assign experiments for student to do and discover properties of vectors.<br /><br />vector, vectors, trig, trigonometry, precalculus, math, mathematicsSun, 25 Mar 2007 06:35:05 GMTLaura Shears Lansing Community CollegeAddition of Ordinates
https://www.merlot.org/merlot/viewMaterial.htm?id=247540
Flash program that tests students’ graphical understanding of addition or subtraction of functions. Uses two randomly generated trig graphs that students then need to add and subtract to find the new graph. Appropriate for use when discussing special cases of graphing trig functions or for use when discussing algebra of functions in a precalculus class even if students are not yet familiar with trig.<br /><br />trigonometry, college algebra, math, precalculus, algebra of functions, addition of ordinates, subtraction of ordinatesSun, 25 Mar 2007 05:17:06 GMTLaura Shears Lansing Community CollegeAngle Between Two Vectors Defined
https://www.merlot.org/merlot/viewMaterial.htm?id=247548
Teaches what is meant by the angle between two vectors. After learning vector addition, many students get confused when asked to find the angle between two vectors. This program clarifies that it is the angle between the tails, not the head and tail.<br /><br />vectors, trig, trigonometry, angle between two vectors, precalculus, math, mathematicsSun, 25 Mar 2007 06:07:17 GMTLaura Shears Lansing Community CollegeCheck Your Triangle Solution
https://www.merlot.org/merlot/viewMaterial.htm?id=248111
Enter 3 parts of a triangle and then enter the number of solutions and then your solution(s) accurate to the hundredths place. This program checks your answer without giving away the answers.<br /><br />trig, trigonometry, triangle, triangles, precalculus, solving triangles, math, mathematicsThu, 29 Mar 2007 15:39:35 GMTLaura Shears Lansing Community CollegePick Triangle Case and Solve Random

https://www.merlot.org/merlot/viewMaterial.htm?id=247551
Allows the student to practice finding various radian measures on the unit circle, both in terms of multiples of key values and in decimal format.<br /><br />trig, trigonometry, unit circle, radian, radian measure, precalculus, math, mathematicsSun, 25 Mar 2007 06:12:00 GMTLaura Shears Lansing Community CollegeRandom Sine Graph
https://www.merlot.org/merlot/viewMaterial.htm?id=247554
Generates random sine graphs. The student needs to figure out the amplitude, period, vertical shift, and phase shift. Next the student figures out the equation.<br /><br />trig, trigonometry, trig graphs, sine graphs, trig graph, sine graph, precalculus, mathematicsSun, 25 Mar 2007 06:26:06 GMTLaura Shears Lansing Community CollegeSolve a Random Triangle
https://www.merlot.org/merlot/viewMaterial.htm?id=247552
Three random parts of a triangle are displayed and then the student is asked to find the number of solutions. Next if there is a solution or two, the student is asked to calculate the solutions.<br /><br />trig, trigonometry, triangle, triangles, solving triangles, precalculus, mathematics, mathSun, 25 Mar 2007 06:18:06 GMTLaura Shears Lansing Community CollegeVector Addition
https://www.merlot.org/merlot/viewMaterial.htm?id=247546
This program teaches how to add vectors geometrically. The student is shown how to add two vectors geometrically and then two random vectors are generated for the student to move and add. Next three random vectors are generated to see if the student can deduce how to add three vectors.<br /><br />vectors, vector addition, trig, trigonometry, precalculus, mathematicsSun, 25 Mar 2007 05:48:58 GMTLaura Shears Lansing Community CollegeVector Definition

https://www.merlot.org/merlot/viewMaterial.htm?id=247561
Art students can experiment with one point perspective of a cube. Students can move the vanishing point around, move the front of the cube and play with a slider to change the length of the side. Students can also switch between isometric view and perspective view.Sun, 25 Mar 2007 07:14:34 GMTLaura Shears Lansing Community CollegeTwo Point Perspective
https://www.merlot.org/merlot/viewMaterial.htm?id=247559
Helps beginning art students learn to draw two point perspective. Students can grab the vanishishing points and move them in or out, up or down. Students can also grab the front corner of the cube to move it around. Students use sliders to decide how what percent of the length of the front edge each side edge should be. Could also be used by a teacher and projected onto a screen or white board to demonstrate simple two point perspective.<br /><br />art, perspective<br />Sun, 25 Mar 2007 07:06:51 GMTLaura Shears Lansing Community College
