These identities arise from the three basic identities along with geometry and a little help from Pythagoras and knowledge of algebraic methods of factoring. These identities are used to reduce integrals so that they can be solved, as well as to find the values for angles that are not specifies...
Often when given a problem, we try to model the scenario using mathematics in the form of words, tables, graphs, and equations. One method we can employ is to adapt the basic graphs of the toolkit functions to build new models for a given scenario. There are systematic ways to alter fun...
