Discover the Derivation of Solid Angle: Short and Simple Method

In summary, solid angle is a measure of the amount of space covered by a three-dimensional object as seen from a specific point. It is important in science as it helps us understand the distribution of energy in space. The derivation of solid angle involves a mathematical process, but a short and simple method is to use the formula Ω = A/r^2, where Ω is the solid angle, A is the area of the surface subtending the angle, and r is the distance from the point to the center of the surface. Solid angle is measured in steradians (sr), which is equal to the area of a unit sphere subtended by a unit area on its surface.

I want to know the derivation of solid angle.

I have found on net. But the derivation is to long, is there any short method?
