WebThe sine of an angle is defined in the context of a right triangle: for the specified angle, it is the ratio of the length of the side that is opposite that angle to (which divided by) the … WebYou could rearrange the concept a bit to get that the sum of the arguments must be 90 degrees for the sides to be equal, since the sine is the same as the cosine of the …
WebThe value of cosec 270° is equal to -1. How to Find the Value of Sin 270 Degrees? The value of sin 270 degrees can be calculated by constructing an angle of 270° with the x-axis, and then finding the coordinates of the corresponding point (0, -1) on the unit circle. The value of sin 270° is equal to the y-coordinate (-1). ∴ sin 270° = -1. WebCommunity Experts online right now. Ask for FREE. ... Ask Your Question Fast!
WebFor example, the sine of an angle is equal to the --Select--- V of its ---Select--- ; the cosine of an angle is equal to the -Select- of its --Select- When a right triangle with a hypotenuse of … WebThe sin of 120 degrees equals the y-coordinate (0.866) of the point of intersection (-0.5, 0.866) of unit circle and r. Hence the value of sin 120° = y = 0.866 (approx) Sin 120° in Terms of Trigonometric Functions Using trigonometry formulas, we can represent the sin 120 degrees as: ± √ (1-cos² (120°)) ± tan 120°/√ (1 + tan² (120°))
WebJun 14, 2024 · The sine function relates a real number t to the y -coordinate of the point where the corresponding angle intercepts the unit circle. More precisely, the sine of an angle t equals the y -value of the endpoint on the unit circle of an arc of length t. In Figure 2.2.3, the sine is equal to y.
Move the mouse around to see how different angles (in radians or degrees) affect sine, cosine and tangent. In this animation the hypotenuse is 1, making the Unit Circle. Notice that the adjacent side and opposite side can be positive or negative, which makes the sine, cosine and tangent change between … See more Sine, Cosine and Tangent are the main functions used in Trigonometry and are based on a Right-Angled Triangle. Before getting stuck into the … See more Sine, Cosine and Tangent (often shortened to sin, cos and tan) are each a ratio of sidesof a right angled triangle: For a given angle θ each ratio … See more Why are these functions important? 1. Because they let us work out angles when we know sides 2. And they let us work out sides when we know angles See more The triangle can be large or small and the ratio of sides stays the same.
