Sine FormulaIn a right-angled triangle, the sine of an angle is the length of the opposite side, divided by the length of the triangle's hypotenuse. Depending upon the quadrants, the sine function can have both positive as well as negative values. Sine has a positive value in the first ...
The definition ofsineis the ratio between the side opposite the angle in question and the hypotenuse (in a right triangle). With the abbreviation sin, sin in math refers to the function to measure an angle using the formula {eq}\frac{opposite}{hypotenuse} {/eq}. ...

Calculate sine by dividing the leg across from the acute angle in the question by the hypotenuse of the triangle. In other words, sin(theta) = O/H, where O is the opposite leg and H is the hypotenuse. What is the sine and cosine formula? The sine formula is sin(theta) = O/H, ...
Here a, b, c are the length of the sides of the triangle, and A, B, C are the angles of the triangle. What are the Different Ways to Represent Sine Rule Formula? Sine law can be represented in the following three ways. These three forms are as given below, a/sinA = b/sinB =...

Sine Formula The sine formula is: sin(α) =opposite/hypotenuse=a/c Thus, the sine of angle α in a righttriangleis equal to the opposite side’s length divided by the hypotenuse. To find the ratio of sine, simply enter the length of the opposite and hypotenuse and simplify. ...
If the sine of an angle in a right triangle is 1/2 and the opposite side is 5, what is the hypotenuse? A. 5 B. 10 C. 15 D. 20 相关知识点: 试题来源: 解析 B。正弦定义为对边/斜边,已知正弦值为 1/2,对边为 5,所以斜边 = 对边÷正弦值 = 5÷(1/2) = 10。
