How can I solve the following problem: Let $f, \pi, g$ accept one, two and three arguments respectively. If you know that $f, \pi, g$ are primitive recursive functions prove that $h$ defined as: $$ \begin{align*} h(0, y) &\simeq f(y) \\ h(x + 1, y) &\simeq g(x, y, h(x, \pi(x, y))) \end{align*} $$ is also primitive recursive function. The definition of primitive recursion I know is: $$ \begin{align*} h(\bar{x}, 0) &\simeq f(\bar{x}) \\ h(\bar{x}, y + 1) &\simeq g(\bar{x}, y, h(...

So you know how we have theorems? For example, a questions gives us a statement and demands us to prove the statement right? Similarly, can we do it for curves too? I mean, if a graph of a curve is given and the question demands us to prove that its...
Answer:
Can't be done in general, because the curve is going to be specific by some finite geometric means,...

Upper bound. For all n > 1: (n+1)^(3/2) < (n+n)^(3/2) = 2^(3/2) * n^(3/2). Lower bound. For all...

Answer:
Your function is f(x) = ln (1 + x) - x if you differenciate it wrt x, then f'(x) = 1/(1+ x) - 1 now...
