In the mathematical theory of categories, a sketch is a category D, together with a set of cones intended to be limits and a set of cocones intended to be colimits. A model of the sketch in a category C is a functor that takes each specified cone to a limit cone in C and each specified cocone to a colimit cocone in C. Morphisms of models are natural transformations. Sketches are a general way of specifying structures on the objects of a category, forming a category-theoretic analog to the logical concept of a theory and its models. They allow multisorted models and models in any category. Sketches were invented in 1968 by Charles Ehresmann, using a different but equivalent definition. There are still other definitions in the research literature. (Wikipedia).

Trigonometry - Sketch an angle using a point
Many times we think of angles floating around in space, but we can connect them to what you already know about graphs by putting them on a coordinate axis. Watch in the examples how we can take a point, and use it to define an angle. For more videos please visit http://www.mysecretmathtu
