An angle’s reference angle is the size angle, [latex]t[/latex], formed by the terminal side of the angle [latex]t[/latex] and the horizontal axis. Reference angles can be used to find the sine and cosine of the original angle. Reference angles can also be used to find the coordinates of a point on a circle. An angle is the union of two rays having a common endpoint. The endpoint is called the vertex of the angle, and the two rays are the sides of the angle. The angle in Figure 2.1.2 is formed from → ED and → EF. Angles can be named using a point on each ray and the vertex, such as angle DEF, or in symbol form ∠DEF.Trigonometry Find the Reference Angle -330 degrees −330° - 330 ° Find an angle that is positive, less than 360° 360 °, and coterminal with −330° - 330 °.

Free math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, just like a math tutor. 360° - 330° = 30°, so the reference angle is 30°. 330° is in quadrant IV, and cosine is positive in quadrant IV, so: Properties of the cosine function. Below are a number of properties of the cosine function that may be helpful to know when working with trigonometric functions.For sin 240 degrees, the angle 240° lies between 180° and 270° (Third Quadrant). Since sine function is negative in the third quadrant, thus sin 240° value = -(√3/2) or -0.8660254. . . Since the sine function is a periodic function, we can represent sin 240° as, sin 240 degrees = sin(240° + n × 360°), n ∈ Z.

asher whitaker golf A unit circle has a radius of one. Cosine is the x coordinate of where you intersected the unit circle, and sine is the y coordinate. Or if you had a vector of magnitude one, it would be cosine of that angle, would be the x component, for the, if we had a unit vector there in that direction. And then sine would be the y component.Trigonometry Find the Reference Angle -330 degrees −330° - 330 ° Find an angle that is positive, less than 360° 360 °, and coterminal with −330° - 330 °.

Exact Form: Decimal Form: Cookies & Privacy fossilized sponge If the terminal side is in the third quadrant, the reference angle is the angle minus 180∘ or π. If the terminal side is in the fourth quadrant, the reference angle is 360∘ or 2π minus the angle. In this example, the angle of 330∘ is in the fourth quadrant, so know that in order to find the reference angle, we must subtract the angle ...The angle 30° lies in the first quadrant. The reference angle is the angle that the given angle makes with the x-axis. When the terminal side of the given angle is in the first quadrant (angles from 0° to 90°), our reference angle is the same as our given angle. So, the reference angle of 30° = 30°.
