Introduction to Trigonometry Trigonometry (from Greek trigonon "triangle" + metron "measure") Want to learn Trigonometry? Here is a quick summary. Follow the links for more, or go to Trigonometry ... is all about triangles. Trigonometry helps us find angles and distances, and is used a lot in science, engineering, video games, and more! Right-Angled Triangle The triangle of most interest is the Another angle is often labeled θ, and the three sides are then called: • Adjacent: adjacent (next to) the angle θ • Opposite: opposite the angle θ • and the longest side is the Hypotenuse Why a Right-Angled 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! Sine, Cosine and Tangent The main functions in trigonometry are They are simply one side of a right-angled triangle divided by another. For any angle " θ": (Sine, Cosine and Tangent are often abbreviated to sin, cos and tan.) Example: How Tall is The Tree? 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): • We know the Hypotenuse • And we want to know the Opposite Sine is the ratio of Opposite / Hypotenuse: sin(45°) = Opposite Hypotenuse ...

It is a branch of Mathematics that deals with the relationships between the lengths and angles of the sides of triangles. A trigonometric equation is an equation involving one or more trigonometric ratios of unknown angles. It is expressed as ratios of sine(sin), cosine(cos), tangent(tan), cotangen
