verify the assertion. (Subspace example) 1) The set of continuous real-valued functions on the interval [0,1] is a subspace of R^[0,1] This is from Linear Algebra Done Right- Sheldon Axler 3rd edition. I don't understand why the solution uses a integral.

3) Prove that the cardinality of the open unit interval, (0,1), is equal to the cardinality of the open unit cube: {(x,y,z) E R^3|0<x<1, 0<y<1, 0<Z<1}. [Hint: Model your argument on Cantor's proof for the interval and the open square. Consider the decimal expansion of the fraction 12/999. It may prove handdy]

In RU (R is the reals, U is the usual topology), prove that any open interval (a, b) is homeomorphic to the interval (0, 1). (Hint: construct a function f : (a, b) → (0, 1) for which f(a) = 0 and f(b) = 1. Show that your map is a homeomorphism by showing that it is a continuous bijection with a continuous inverse.)

Prove that the discrete topology on X is the same as the metric topology induced by the discrete metric. Where metric topology is defined as: If (X,d) is a metric space, then consider the collection T of all open subsets of X. Then (X,T) is topological space. This topology is called the metric topology on X induced by d.
