The thing which can sometimes be confusing is the difference between the reference angle and coterminal angles definitions. Remember that they are not the same thing - the reference angle is the angle between the terminal side of the angle and the x-axis, ... Coterminal angle of 330 ° 330\degree 330 ...If two angles are drawn, they are coterminal if both their terminal sides are in the same place - that is, they lie on top of each other. In the figure above, drag A or D until this happens. If the angles are the same, say both 60°, they are obviously coterminal. But the angles can have different measures and still be coterminal.Reference Angle. When an angle is drawn on the coordinate plane with a vertex at the origin, the reference angle is the angle between the terminal side of the angle and the x x -axis. The reference angle is always between 0 0 and \frac {\pi} {2} 2π radians (or between 0 0 and 90 90 degrees). In both these diagrams, the blue angle y y is a ...

To convert degrees to radians, multiply by π 180° π 180 °, since a full circle is 360° 360 ° or 2π 2 π radians. 315°⋅ π 180° 315 ° ⋅ π 180 ° radians. Cancel the common factor of 45 45. Tap for more steps... 7⋅ π 4 7 ⋅ π 4 radians. Combine 7 7 and π 4 π 4. 7π 4 7 π 4 radians. Free math problem solver answers your ...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 ... See full list on piday.org Well, the reference angle is the angle [the one which is the smallest] ... How do you express as a trigonometric function of an angle in quadrant 1 given sec(330)?For sin 300 degrees, the angle 300° lies between 270° and 360° (Fourth Quadrant ). Since sine function is negative in the fourth quadrant, thus sin 300° value = - (√3/2) or -0.8660254. . . ⇒ sin 300° = sin 660° = sin 1020°, and so on. Note: Since, sine is an odd function, the value of sin (-300°) = -sin (300°).
