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.

SteveThe law of sines is used to find missing values in triangles. The formula is a/sinA=b/sinB=c/sinC. The idea behind the equation is that the larger an angle is the larger the side across from it will be and the smaller the angle the smaller the side across from it will be. Once you have set up your equation you can easily solve your equation with some simple algebra and a calculator.

Can the sine law be used with a acute triangle?
Yes.
What careers use the law of sine and cosine?
mechanical engineers, land surveyors, math teachers, and registered nurses.
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 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.
What is sine infinity?
Sine does not converge but oscillates. As a result sine does not tend to a limit as its argument tends to infinity. So sine(infinity) is not defined.
