WebThe angles that they're picking are ones that can be made by adding angles that are easy to remember, namely pi/6, pi/4, pi/3, and pi/2 (30, 45, 60, and 90, respectively) and their multiples. You can use angle addition to quickly find the trig values of, say, 75 degrees, since it's easy to see that 45+30=75. WebThe sine calculator allows through the sin function to calculate online the sine sine of an angle in radians, you must first select the desired unit by clicking on the options button calculation module. After that, you can start your calculations. To calculate sine online of π 6, enter sin ( π 6), after calculation, the result 1 2 is returned.

WebSin 11pi/6 Using Unit Circle. To find the value of sin 11π/6 using the unit circle: Rotate ‘r’ anticlockwise to form 11pi/6 angle with the positive x-axis. The sin of 11pi/6 equals the y-coordinate (-0.5) of the point of intersection (0.866, -0.5) of unit circle and r. Hence the value of sin 11pi/6 = y = -0.5. WebThe value of sin 11pi/6 in decimal is -0.5. Sin 11pi/6 can also be expressed using the equivalent of the given angle (11pi/6) in degrees (330°). We know, using radian to degree … Websin((2pi/365)t) = 22/52 = .42307 sine of an angle is the y value of the radius when it is at that angle, so it is even less than sin(pi/6), so we know that at least. This also means it is in the domain of arcsin, which is good. sin((2pi/365)t) = 22/52 = .42307 inverse sine or arcsin of both sides 2pi/365 t = arcsin(22/52) divide both sides by ... how to speak to ee
