What is sine in math?
Sine is a law in math that helps you find the length or angles in a triangle.Sin Equals:1/YLaw of Sines:Sin A/a = SinB/b = SinC/cCosine, tangent, cotangent, secant and cosecant are also used to find sides and angles of a triangle.
How do you find two missing sides of a right triangle?
If you have all three angles, you can use the law of sines, which states that the ratio of the sine of one angle is to it's opposite side as the sine of another angle is to it's opposite side.
How does one differentiate between the sine rule and the sine ratio?
The sine rule(also known as the "law of sines") is: a/sin A = b/sin B = c/sin C where the uppercase letters represent angles of a triangle and the lowercase letters represent the sides opposite the angles (side "a" is opposite angle "A", and so on.) Sine Ratio(for angles of right triangles): Sine of an angle = side opposite the angle/hypotenuse written as sin=opp/hyp.
How do you find length of scalene triangle?
Usually, you are given at least a length and an angle Using these two known parts of a scalene triangle Imply the sine laws SinA/a = SinB/b = SinC/c Where A is the angle, and a is the length You need to know at least three parts, either two angles and a side, or two sides and an angle to find the unknown using the above pattern. Use two out of the three equated sine equations above with your known values * * * * * Original answerer replies: It is not much help to give an answer that suggests using the sine law when it may not be of any help. The proper answer is that it will all depend on what you are given. And that is the bottom line. You cannot assume that you are given "at least a length and an angle". You could be given two lengths and an altitude, for example. In that case the sine law would be useless. Or you could be given two sides and a median - again no help from the sine law. In any of these cases, some hard trigonometry is required before you can get to the answer. Furthermore, if you are given two sides and the included angle, you have a, b and C or sin(C). So you cannot evaluate any of the three ratios to use the sine rule because you have only one of the two components in each ratio. Alternatively, if you have two sides and an angle other than the included angle, you have the "ambiguous case" where the triangle can have two possible shapes. In short, I believe that the sine rule cannot help unless you have a lot more information about the triangle.
What is Law of the sine?
The law of sines is a statement about arbitrary triangles in the plane.The law of sines states that in any right triangle, the ratio of the opposite side length to the length of the hypotenuse (relative to an acute angle) is always relative to the size of the angle. Put more simply, it means that if you take the sine of an angle, the value will be equal to the length of the opposite side divided by the length of the hypotenuse. The practical application of this is when you know the length of only one side and the measure of one angle (other than the right angle) you can determine the other sides and the remaining angle.The law of sines states that in any right triangle, the ratio of the opposite side length to the length of the hypotenuse (relative to an acute angle) is always relative to the size of the angle.

Is sine law applicable in acute triangle?
Yes
Can the sine law be usd in a right triangle?
Yes, the law of sines can be used in a right triangle. The law applies to any arbitrary triangle.
When would you use the law of sines or law of cosines instead of a trigonometric ratio?
Trigonometric ratios, by themselves, can only be used for right angled triangles. The law of cosines or the sine law can be used for any triangle.
How do you find the perimeter of a triangle if you only know the angles and one of the lengths?
The law of tangents can be used to determine another side length; the sine rule can then be used to determine the third side length.

What are real life applications of the law of sines?
Land surveying makes an extensive use of the sine and cosine law. The idea is to subdivide the land into many triangles and to measure one side and two angels of each triangle. With the sine law the other two sides can be computed. The Mount Everest was found by this method to be the highest mountain on planet earth.

How does one differentiate between the sine rule and the sine ratio?
The sine rule(also known as the "law of sines") is: a/sin A = b/sin B = c/sin C where the uppercase letters represent angles of a triangle and the lowercase letters represent the sides opposite the angles (side "a" is opposite angle "A", and so on.) Sine Ratio(for angles of right triangles): Sine of an angle = side opposite the angle/hypotenuse written as sin=opp/hyp.
What is the definition of Cosine and sine law in physics?
The law of sines states the in a triangle with sides of length a, b, and c, and angles of A, B, and C where each angle's letter corresponds with the side opposite it, that Sin(A)/a = Sin(B)/b = Sin(C)/c. The law of cosines states that for the same triangle, c2 = a2 + b2 -2abCos(C).
