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.
How do you find the missing length of a triangle?
You use the Pythagoras Theorem if it is a right-angled triangle. a squared + b squared = h (longest side, diagonal) squared, then square root h to find the longest side. if it is not a right angled triangle, then use the Sine or Cosine rule. Sine rule for: two angles and any one side or two sides and an angle that is not in between the sides. Cosine rule for: all three sides (but then you do not need to find a missing side) or two sides and an angle that is in between.
What is the sine of 20 degrees?
sine-1(0.3420201433) = 20 degrees
Is it is necessary to be a right angle triangle to use sine rule?
No. Sine rule (and cosine rule) apply to all triangles in Euclidean space (plane geometry). A simplification occurs when there is a right angle because the sine of the right angle is 1 and the cosine is 0. Thus you get Pythagoras theorem for right triangles.
How does one differentiate between the sine rule and the cosine rule?
The sine rule is a comparison of ratios: (sin A)/a = (sin B)/b = (sin C)/c. The cosine rule looks similar to the theorem of Pythagoras: c2 = a2 + b2 - 2ab cos C.
What is the inverse sine of 1.5?
The previous answers are wrong.The answer is 1.5707963267949-0.962423650119207i.
What is the length of the side of a triangular fence if one side is 100 feet and the other side is 200 feet?
Use the sine rule to find the the length of third side. Sine rule: a/sinA = b/sinB = c/sinC
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 proportion do you use to find the length of the third side triangle XYZ?
The answer depends on the information that you have: it could be the sine rule or the cosine rule.
What is the figure of Megan Fox?
17 and a half.... It's calculated using the angle of her waist, subtended outwards and taking that sine value and also the sine value of her curvature, you can calculate her figure. There's some complex maths involved.
What are some contributions of Aryabhata to maths?
# HE USED LETTERS FOR UNKNOWN QUANTITIES. # WORKED ON THE APPROXIMATION OF "PI" TO 4 DECIMAL PLACES AND DEFINED IT AS IRRATIONAL. # GAVE THE AREA OF TRIANGLE AND CIRCLE. # DEFINED SINE, COSINE, VERSINE AND INVERSE SINE.
Fourier analysis shows that the saw tooth wave consists of which type of wave?
Fourier analysis shows that the saw wave is constructed through manipulation of a sine wave, I can't remember the maths behind it but it's definitely a sine wave.
What theorem states that if three forces acting at a point they are in equilibrium then each force is proportional to the sine of the angle between the other two?
The result is a direct consequence of the sine rule.
How is sin 3060 degree equals 0 please tell according to class XI maths?
3060 degrees is eight and a half revolutions. So the sine of 3060 degrees is the same as the sine of 180 degrees (half a revolution) sin 180 = 0
Is anyone good at phyics i need help with some Cosine and Sine Problems?
We do not have private question and answer sessions. This is a community question and answer system. Ask your questions directly. ============================================ Another contributor added: You can get your answers here, if you post the questions one at a time. If you do that, you'll have all of your answers, probably within a week. But you won't be able to solve the problems, any more than you are now, so the answers won't do you any good. By a long shot, the very best person to help you with these problems is your teacher.
