Trigonometric Relations and Trigonometric formula for calculus

Trigonometric Relations is relation between each angle of trigonometric function like cos with sin, sin with tang, sinxsin + cosxcos and othes relation
to learn more about trigonometric function from the introduction online, i recommended this site
this site have enough resources about trigonometric function like :

    Definitions and basics

  • Trigonometric circle and angles
  • Trigonometric numbers of a real number t
  • Basic formulas

    Trigonometric functions

  • The sine function
  • The cosine function
  • The tangent function
  • The cotangent function

    Sum formulas like

  • cos(u - v)
  • cos(u + v)
  • sin(u - v)
  • sin(u + v)
  • tan(u + v)
  • tan(u - v)

pdf version of trigonometric relation you can download at link below, altough is not complete list like online version from

and trygonometric function for calculus identities you can download at link below

the complete explanation and tutorial about trigonometric identities you can download tutorial that written by Thomas E. Price, from Department of Theoretical and Applied Mathematics, THE UNIVERSITY OF AKRON.
