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 sin on a scientific calculator?
It is short for sine (pronouncing it as sin annoys many maths teachers). Check this site out for detailed info. http://www.clarku.edu/~djoyce/trig/
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.
What is sine of angle 22.5 degrees?
The sine of 22.5 degrees is 0.383
What is the sine of 20 degrees?
sine-1(0.3420201433) = 20 degrees
