What is ecological sin?
ecological sin is a sin of every individual against the environment....
What is the formula of 2sinxcosx?
In trigonometry, sin(x)cos(y)=(sin(x+y)+sin(x-y))/2.
Why is sin used in the refraction of light?
Light follows the Law of Sines in refraction and reflection' sin(I)/VI = sin(T)/VT=sin(R)=VI.
How is the index of refraction of a substance related to the speed of light in the substance?
The substance's index of refraction isSpeed of light in vacuum / Speed of light in the substance
A combination of waves from a larger wave?
smaller in amplitude: sin(x), -3/2 sin(x) cancel out to become -sin(x)/2, which has a smaller amplitude smaller wavelength: sin(x), sin(x), "combine" them by multiplying together. The wavelength is reduced by 2 If you are looking for an addition of waves that gets the smaller wavelength of a sine wave, here is the simplest one I can find. It is an infinite addition, and the result is sin(2x), a wave that has a smaller wavelength than the individual waves: sum from k=0 to infinity of sin(k*pi/2+z0)(2x-z0)k / k!
Is it possible to have a triangle whose angle measures are in the ratio 3 to 4 to 5 and whose side lengths are the same ratio?
No. If the angles are in the ratio 3:4:5, the sides will be in the ratio sin(3):sin(4):sin(5) - NOT in the ratio 3:4:5.
What is the unit of sin θ?
Sin is a ratio and so has no units.
Is all sin the same?
I think so. I have always been taught that a sin is the same all around. Lying is the same as murder. A sin is a wrongdoing that hurts God. Jesus died for all sins, big and little.
What elements of thre romanticism is best represented in London?
The city is a place of misery and sin - apex ;) the game
Sin cos?
"Sin" stands for "sinus". The sinus of any angle is defined, in a rectangle triangle, as the ratio of the side opposed to the angle and the hypotenuse. The sinus is useful because it is unique to any angle, which means that the ratio of the opposite side and the hypotenuse in any rectangle triangle is always the same given a certain angle. "Cos" stands for "cosinus". The cosinus of any angle is defined, in a rectangle triangle, as the ratio of the side adjacent to the angle and the hypotenuse. Like the sinus of an angle, the cosinus of an angle will always be constant, which means that, given a certain angle, the ratio will always be the same even if the triangles don't have the same size. Sinus and Cosinus are very useful to determine missing informations in rectangle triangles. In fact, with only two informations (angle and side), you can find every information on this triangle.
What answer in sin cos tan?
sin is short for sine. Sin(x) means the ratio of the side of a right triange opposite the angle 'x' divided by the length of the hypotenuse. cos is short for cosine. Cos(x) is equal to the similar ratio of the side adjacent to the angle 'x' divided by the length of the hypotenuse. tan is short for tangent. Tan(x) is equal to the ratio of the opposite side divided by the adjacent side. This is the same as sin(x)/cos(x).
What does sin stand for on a calulator?
The "sin" button on a calculator gives the sine trigonometric ratio of the given angle.
What is a cosecant ratio?
cosecant(x) = 1/sin(x)
What is the 3 equivalent ratios to compare to 3 and 4?
Just as in the case of a fraction, you can expand such a ratio by multiplying both numbers with the same non-zero number. It's easiest if you use integers for this.
Will Anger be a sin?
Yes. Anger is always gonna be a sin.
Why the value of tan A is always less than one?
The values of tan are limitless (that is to say, within [-inf, inf]). However, sin and cos ratios are between -1 and 1. Think about it: sin = opposite/hypotenuse. Since hypotenuse is always larger than or equal to opposite, sin must always be less than 1. Same with cos.
For any nonquadrantal angle sin and csc will have the same sign eplain why this is so?
the sin and csc functions are reciprocals, & reciprocals always have the same sign, since their product is 1, a positive number (straight out the back of a precalc book)
