a number or figure that never changes
Constant.
The probability is 1. The letters in the word mathematics are all constants, not variables!
The question is erroneous because you cannot measure anything with mathematics. Mathematics is not an empirical science, it makes no measurements. You can derive the speed of light mathematically from other constants such as various constant having to do with electromagnetism but these constant will have to be measured separately (and not through mathematics).
Acceleration may be constant or variable. Of course, in many high-school level problems, it is assumed to be constant, because in that case, the mathematics is simpler.
The reduced Planck constant simplifies the mathematics found in quantum physics calculations by adding a 2pi term into it. Instead of worrying about that 2pi constant, formulas using the reduced Plank constant have it built in.
Natural Log; It's a logarithm with a base of e, a natural constant.
it gives the ratio of perimeter to that of diameter of a circle which is universal constant.
In mathematics, two quantities are proportional if they vary in such a way that one of them is a constant multiple of the other.
Yes. An object moving at constant velocity has zero acceleration. The constant velocity van be any constant including zero velocity. Mathematics acceleration a=dv/dt = 0. Solving this gives v = constant.
Since I am a constant, not a variable, there can be no correlation. The calculation would entail division by zero, which is not permitted.
In mathematics, a constant rate of change is called a slope. For linear functions, the slope would describe the curve of the function. The world "constant" in this context means the slope and therefore angle of the curve will not change.
A constant is a fixed value that does not change during a specific process or calculation. In mathematics and science, constants are used to represent specific values such as the speed of light or the gravitational constant.
