Note that sin-60° is periodic: sin (-60° + n …The angles are determined using the primary functions of sin, cos, and tan, while the secondary functions of cosecant, secant, and cot are obtained from the primary functions. 0°, 30°, 45°, 60°, 90°, 180°, 270°, and 360° are the most common degrees.Solution: Observe the given image. An angle of 60 degrees is an angle that represents one-sixth of a complete angle. Complete angle is a 360-degree angle. So, a total of six 60-degree angles are present in one complete angle. Example 3: Construct an angle of 60 degrees using a protractor. Solution:Answer: sin (37°) = 0.6018150232. Note: angle unit is set to degrees. Use our sin (x) calculator to find the sine of 37 degrees - sin (37 °) - or the sine of any angle in degrees and in radians.

Cosine definition. Cosine is one of the most basic trigonometric functions. It may be defined based on a right triangle or unit circle, in an analogical way as the sine is defined: The cosine of an angle is the length of the adjacent side divided by the length of the hypotenuse. cos(α) = adjacent / hypotenuse = b / c.

For memorising cos 0°, cos 30°, cos 45°, cos 60° and cos 90°. Cos is the opposite of sin. We should learn it like. cos 0° = sin 90° = 1. cos 30° = sin 60° = √3/2. cos 45° = sin 45° = 1/√2. cos 60° = sin 30° = 1/2. cos 90° = sin 0° = 0. So, for cos, it will be like.

Sine, Cosine and Tangent. Sine, Cosine and Tangent (often shortened to sin, cos and tan) are each a ratio of sides of a right angled triangle: For a given angle θ each ratio stays the same no matter how big or small the triangle is. To calculate them: Divide the length of one side by another side 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)The angles in Sine Cosine Tangent are given in the order of 0°, 30°, 45°, 60°, and 90°. You can remember the value of Sine-like this 0/√2, 1/√2, 2/√2, 3/√2, 4/√2. The row of cosine is similar to the row of sine just in reverse order. Each value of tangent can be obtained by dividing the sine values by cosine as Tan = Sin/Cos.Therefore, Sin 30 degree equals to the fractional value of 1/ 2. Sin 30° = 1 / 2. Therefore, sin 30 value is 1/2. In the same way, we can derive other values of sin degrees like 0°, 30°, 45°, 60°, 90°,180°, 270° and 360°.
