Best ResponseYou've already chosen the best response.0ok... when we derivative a function we always do this for example: the derivative of x^1/2 = 1/2(x)^(1/21) = 1/2(x)^1/2

Best ResponseYou've already chosen the best response.0apply that for you example: the derivative of (r^2+4)^1/2 = (1/2)(2r)(r^2+4)^(1/21) = (r)(r^2+4)^(1/2)
