I presume mean the "fine structure constant," which is abbreviated as alpha.

It is the ratio of the square of the electric charge, divided by Planck's Constant and the speed of light. It has no units, and thus does not depend on which system of units you are using. More importantly, it involves all three of the most fundamental numbers of our Universe.

Whether this number has any special meaning in our Universe is still a matter of discussion. It may be nothing more than a unit-less ratio of three fundamental numbers, with no meaning beyond that fact.

multiply them together. u mean alpha and beta as x and y right?

Ya mum Constant are numbers which has no units (EG: PYE which is 22/7) . They are just numbers. Where as coefficients have units. . where as Coefficient like alpha the thermal coefficient has units .It is so many mm/meter/ deg C

According to Wolfram Alpha, input:integral csc x it is -log[cot(x) + csc(x)] + constant You can verify this by taking the derivative of the purported integral.

There is no evidence to suggest that the gravitational constant 'G' is not the exact same number everywhere in the universe.

Alpha and beta are particles and are ionizing but they are not rays. Their velocity varies with the energy that they are ejected with from unstable atoms. Gamma rays, as well as x-rays and the entire range of the electromagnetic spectrum, have a constant velocity of the speed of light or they don't exist at all.

Any letter of the Greek or Roman alphabet, or any other alphabet can be used to represent a variable. There are also non-alpha symbols, for example for the Dirac constant (or reduced Planck constant).

It's not. The coefficient of static friction is only equal to the tangent of the angle of incline at the maximum angle before the object begins to slide. At this point static friction equals the component of the weight along the incline (weight X sin alpha). Static friction is given by the coefficient of static friction times the normal force (weight X cos alpha) fs = us N = us mg cos(alpha) Wx =mg sin(alpha) fs = Wx us mg cos(alpha) = mg sin(alpha) us = [sin(alpha)] / [cos(alpha)] = tan(alpha) Similarly, the coefficient of kinetic friction equals the tangent of the angle of incline only if the object is sliding down the incline at constant velocity (net force equals zero). If the object is accelerating along the incline (make this the x axis): Fnet, x = Wx - f max = mg sin(alpha) - uk mg cos(alpha) uk = [g sin(alpha) - ax] / [g cos(alpha)]
