Mathematics: Form and Function Saunders Mac Lane
Publisher: Springer

And later on in his Mathematics: Form and Function (1986). (c) $\sin z =(e^{iz}-e^{-iz})/2 ∀z∈\mathbb{C}$. A linear functional {f} is just a linear map from {V} to {\mathbb{R}} . This is a very intuitive way to feel and learn math. Posted on May 14th, 2012 by Mary Lord. (b) $\sin^2z+\cos^2z=1 ∀z∈\mathbb{C}$. The considerations that motivate the ideas of “naturalness” in algebraic geometry and category theory are expressed in the Preface to John Lee's Introduction to Smooth Manifolds, and then fleshed-out in Mac Lane's Mathematics: Form and Function. Every such space has a dual space {V^{*}} of the same dimension: the dual is nothing more than all the linear functionals defined on the vector space. Theorem (classically equivalent form): All functions are continuous. While manipulating the elements of art – line, shape, color and form, one is also playing with mathematical functions, geometry, numbers and graphs. Pick out the true statements: (a) $|\sin z|≤1 ∀z∈\mathbb{C}$. With interviews with MIT scientists, professors, artists and theorists, the director shows a universal nature between art and mathematics; form and function. When constructive mathematicians says that “all functions are continuous” they have something even better in mind. Mathematical ideas do not live fully until they are presented clearly, and we never quite achieve that ultimate clarity.
