WebTrigonometric functions, which are properties of angles and depend on angle measure, are also explained using similarity relationships. Students determine when to use … Webexplain why the tangent of 45° is always 1. use examples and nonexamples to make conjectures about special right triangles. the short side of a 30-60-90 triangle is always half the length of the hypotenuse. the sine of 30° is always ½ and, conversely, if the sine is ½ then the angle is 30°. the cosine of 60° is always ½ and, conversely ...

5.3 Trigonometric Functions of Any Angle - Big Ideas Learning
WebExamples include electrical applications (alternating current), sound and radio waves, simple harmonic motion (such as a swinging pendulum), the trajectory of satellites, or the rising and falling of the tide. WebTrigonometric Functions of Any Angle You can generalize the right-triangle defi nitions of trigonometric functions so that they apply to any angle in standard position. Evaluating … WebTrigonometric functions can also be defined as coordinate values on a unit circle. A unit circle is a circle of radius 1 centered at the origin. ... For example, 30° is the reference angle of 210° with sine values sin(30°)= and sin(210°)=. We can see that the sine values of both have a magnitude of , albeit they have different signs. kids bingo cards free
