Does anybody know what came first for trigonometric functions?

  1. Jun 19, 2011 #1
    I want a timeline for trigonometric function and how it was developed. Just like who created it and stuff like that. Did the greeks know about trigonometric functions? Is a tangent in calculus the same as a tangent in trigonometry and the function os a trigonometry? How do trigonometric functions apply to right angle triangles?
