2019年1月26日 · sine 150 = opposite side over hypotenuse = 1/2 over 1 = 1/2. 150 degrees is 180-30 degrees. The right triangle in the 3rd quadrant is 30 degrees when you drop a vertical down from the end of

2025年1月18日 · To find the value of sin 150° - cos 180°: *Step 1: Find the value of sin 150°* Using the trigonometric identity sin (180° - x) = sin x, we can rewrite sin 150° as sin (180° - 30°) = sin 30°. We know that sin 30° = 1/2. *Step 2: Find the value of cos 180°* We know that cos 180° = -1. *Step 3: Subtract cos 180° from sin 150°*

2019年4月14日 · Calculate sin(150)° Since our angle is greater than 90 and less than or equal to 180 degrees, it is located in Quadrant 2. In the second quadrant, the values for sin are positive only. 150 is an obtuse angle since it is greater than 90° sin(150)=1/2

Answer to Question Compute the exact value of sin(150° + 45°).

2020年10月10日 · Sin 30 = sin 150 = ½. Both are equal because the reference angle for 150 is equal to 30 for the triangle formed in the unit circle. The reference angle is formed when the perpendicular is dropped from the unit circle to the x-axis, which forms a right triangle. Since, the angle 150 degrees lies on the IInd quadrant, therefore the value of sin ...
