【解析】 Simplify $$ \sqrt { \frac { A } { 4 \pi } } $$. $$ r = \frac { \sqrt { A \pi } } { 2 \pi } $$ To reurite as a function of A, write the equa tion so that, is by itself on one side of the equal sign and an expression involving only A is on ...
In mathematics, a square root function is defined as a one-to-one function that takes a positive number as an input and returns the square root of the given input number. f(x) = √x For example, if x=4, then the function returns the output value as 2. Note: The square root of ...

A derivative of a function tells us how fast this function changes with its argument. One of the simplest examples in physics is the position of an object and its velocity (the rate of change of position). Let's say that the function x(t) describes how the distance of the moving car ...
