Want to learn Trigonometry? Here is a quick summary. Follow the links for more, or go to Trigonometry Index. Trigonometry helps us find angles and distances, and algebra & trigonometry used a lot in science, engineering, video games, and more! The triangle of most interest is the right-angled triangle. The right angle is shown by the little box in the corner:. Another angle is often labeled θand the three sides are then called:. The main functions in trigonometry are Sine, Cosine and Tangent.
Sine, Cosine and Tangent are often abbreviated to sin, cos and tan. The triangle could be larger, smaller or turned around, but that angle will always have that ratio. We can't reach the top of the tree, so we walk away and measure an angle using a protractor and distance using a laser :. What does the 0. It is the ratio of the side lengths, so the Opposite is about 0. Play with this for a while move the mouse around and get familiar with values of sine, cosine and tangent for different angles, such as 0°, 30°, 45°, 60° and 90°, algebra & trigonometry.
Also try °, °, °, °, algebra & trigonometry, ° etc, and notice that positions can be positive or negative by the rules of Cartesian coordinatesso the sine, cosine and tangent change between positive and negative also. Note: you can see the nice graphs made by sine, cosine and tangent.
Angles can be in Degrees or Radians. Here are some examples:. Because the angle is rotating around and around the circle the Sine, Cosine and Tangent functions repeat once every full rotation see Amplitude, Period, Phase Shift and Frequency.
When we want to calculate the function for an angle larger than a full rotation of ° 2 π radians we algebra & trigonometry as many full rotations as needed to bring it back below ° 2 π radians :. rad ians. It helps us in Solving Triangles. Angle C can be found using angles of a triangle add to ° :.
When we know any 3 of the sides or angles we can find the algebra & trigonometry 3 except for the three angles case. See Solving Triangles for more details. Similar to Sine, Cosine and Tangent, there are three other trigonometric functions which are made by dividing one side by another:. The Trigonometric Identities are equations that are true for all right-angled triangles. The Triangle Identities are equations that are true for all triangles they don't have to have a right angle.
Why a Algebra & trigonometry Triangle? Why is this triangle so important? Imagine we can measure along and up but want to know the direct distance and angle: Trigonometry can find that missing angle and distance. Or maybe we have a distance and angle and need to "plot the dot" along and up: Questions like these are common in engineering, computer animation and more. And trigonometry gives the answers! Example: What is the sine of 35°?
Example: How Tall is The Tree? We can now put 0. in place of sin 45° : 0. We know: 0. Example: what is the cosine of °? Trigonometry Index Sine, algebra & trigonometry, Cosine and Tangent Unit Circle Algebra Index, algebra & trigonometry.
