The function is particularly useful in deriving annual payment amounts and understanding complex financial scenarios. Its application extends to various financial calculations, enhancing accuracy and efficiency. Overall, the Lambert W function serves as a valuable tool in financial mathematics.
Seemingly by some mathematical coincidence, a hexagon of sides 2,2,7,7, 11, and 11 can be inscribed in a circle of radius 7. The other day I saw a math problem on line, which they said came from a Polish Olympiad, where you compute the length x of the 3rd side which is the same as the radius, so that the sides of length 2,x, and 11 are inscribed on the arc of a semi-circle. The law of cosines applied twice gives the answer for x of exactly 7, but the arithmetic is so complex that the...
