Reference angle of 330
Standard position of an angle - trigonometry. In trigonometry an angle is usually drawn in what is called the "standard position" as shown below. In this position, the vertex of the angle (B) is on the origin of the x and y axis. One side of the angle is always fixed along the positive x-axis - that is, going to the right along the axis in the ...For example, 30° is the reference angle of 150°, and their tangents both have a magnitude of , albeit they have different signs, since tangent is positive in quadrant I but negative in quadrant II. Because all angles have a reference angle, we really only need to know the values of tan ... 690° - 360° = 330 ...

Recall that an angle’s reference angle is the acute angle, t, t, formed by the terminal side of the angle t t and the horizontal axis. A reference angle is always an angle between 0 0 and 90° , 90° , or 0 0 and π 2 π 2 radians.Trigonometry. Find the Reference Angle 390 degrees. 390° 390 °. Find an angle that is positive, less than 360° 360 °, and coterminal with 390° 390 °. Tap for more steps... 30° 30 °. Since 30° 30 ° is in the first quadrant, the reference angle is 30° 30 °. 30° 30 °. Free math problem solver answers your algebra, geometry ... Aug 3, 2023 · So, if the given angle is 310°, then its reference angle is (360° – 310° = 50°). Hence, Reference Angle = 360° – Given Angle. 2) When Calculated in Radians. When calculated in radians: 180° = π, 360° = 2π, 270 = 2π/2, and 90° = π/2. Thus, the formulas become: Case 1: (For Angles between 0° to 90°) – First quadrant. For cos 150 degrees, the angle 150° lies between 90° and 180° (Second Quadrant). Since cosine function is negative in the second quadrant, thus cos 150° value = −√3/2 or -0.8660254. . . Since the cosine function is a periodic function, we can represent cos 150° as, cos 150 degrees = cos(150° + n × 360°), n ∈ Z.
To draw a 360° angle, we calculate that \displaystyle \frac {360^\circ } {360^\circ }=1 360∘360∘ = 1. So the terminal side will be 1 complete rotation around the circle, moving counterclockwise from the positive x -axis. In this case, the initial side and the terminal side overlap. Since we define an angle in standard position by its ...Trigonometry. Find the Reference Angle -760. −760 - 760.

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.The value of tan 330 degrees can be calculated by constructing an angle of 330° with the x-axis, and then finding the coordinates of the corresponding point (0.866, -0.5) on the unit circle. The value of tan 330° is equal to the y-coordinate (-0.5) divided by the x-coordinate (0.866). ∴ tan 330° = -1/√3 or -0.5774.
