4434Key Radian Values on the Unit Circle
http://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.trig, unit circle, radian measure, math, precalculus, trigonometryVector Drawing Board
http://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.vector, vectors, trig, trigonometry, precalculus, math, mathematicsAddition of Ordinates
http://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.trigonometry, college algebra, math, precalculus, algebra of functions, addition of ordinates, subtraction of ordinatesAngle Between Two Vectors Defined
http://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.vectors, trig, trigonometry, angle between two vectors, precalculus, math, mathematicsCheck Your Triangle Solution
http://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.trig, trigonometry, triangle, triangles, precalculus, solving triangles, math, mathematicsOne Point Perspective
http://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.Pick Triangle Case and Solve Random
http://www.merlot.org/merlot/viewMaterial.htm?id=248139
Pick what kind of triangle you would like to solve and the program will generate a random triangle of that type.trig, triangles, random triangles, trigonometry, precalc, precalculusRadian Target Practice
http://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.trig, trigonometry, unit circle, radian, radian measure, precalculus, math, mathematicsRandom Sine Graph
http://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.trig, trigonometry, trig graphs, sine graphs, trig graph, sine graph, precalculus, mathematicsSolve a Random Triangle
http://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.trig, trigonometry, triangle, triangles, solving triangles, precalculus, mathematics, math
