Since sine function is positive in the first quadrant, thus sin 56° value = 0.8290375. . . ⇒ sin 56° = sin 416° = sin 776°, and so on. Note: Since, sine is an odd function, the value of sin (-56°) = -sin (56°)., To find the value of sin 54 degrees using the unit circle: Rotate ‘r’ anticlockwise to form a 54° angle with the positive x-axis. The sin of 54 degrees equals the y-coordinate (0.809) of the point of intersection (0.5878, 0.809) of unit circle and …, sin 75 ∘ can be expressed as, sin 75 ∘ = sin (45 ∘ + 30 ∘) We know that sin ⁡ (A + B) = sin ⁡ A cos ⁡ B + cos ⁡ A sin ⁡ B. So by applying the above formula we get, sin 75 ∘ = sin 45 ∘ cos 30 ∘ + cos 45 ∘ sin 30 ∘. As, sin 45 ∘ = 1 2, cos 30 ∘ = 3 2 =, cos 45 ∘ = 1 2 and sin 30 ∘ = 1 2. By substituting the ... , \sin (x)+\sin (\frac{x}{2})=0,\:0\le \:x\le \:2\pi \cos (x)-\sin (x)=0 ; 3\tan ^3(A)-\tan (A)=0,\:A\in \:\left[0,\:360\right] \sin (75)\cos (15) \sin (120) \csc (-\frac{53\pi }{6}) prove\:\tan^2(x)-\sin^2(x)=\tan^2(x)\sin^2(x) prove\:\cot(2x)=\frac{1-\tan^2(x)}{2\tan(x)} prove\:\csc(2x)=\frac{\sec(x)}{2\sin(x)} Show More, The formula to convert radians to degrees: degrees = radians * 180 / π What is cotangent equal to? The cotangent function (cot(x)), is the reciprocal of the tangent function.cot(x) = cos(x) / sin(x), InvestorPlace - Stock Market News, Stock Advice & Trading Tips Environmental, social, governance (ESG) investing has been a major theme in rec... InvestorPlace - Stock Market N..., sin 37° = 0.60182. sin 37 degrees = 0.60182. The sin of 37 degrees is 0.60182, the same as sin of 37 degrees in radians. To obtain 37 degrees in radian multiply 37° by π / 180° = 37/180 π. Sin 37degrees = sin (37/180 × π). Our results of sin37° have been rounded to five decimal places. If you want sine 37° with higher accuracy, then ..., Free math problem solver answers your trigonometry homework questions with step-by-step explanations., Precalculus. Find the Exact Value sin (67.5) sin(67.5) sin ( 67.5) Rewrite 67.5 67.5 as an angle where the values of the six trigonometric functions are known divided by 2 2. sin(135 2) sin ( 135 2) Apply the sine half - angle identity. ±√ 1−cos(135) 2 ± 1 - cos ( 135) 2. Change the ± ± to + + because sine is positive in the first quadrant.
