can someone explain cosine sine and tangent for me? and what situations its used in had how to calcualte it and what are the equations i hav

Sine, Cosine and Tangent are the main functions used in Trigonometry and are based on a Right-Angled Triangle. Before getting stuck into the functions, it helps to give a name to each side of a right triangle: "Opposite" is opposite to the angle θ "Adjacent" is adjacent (next to) to the angle θ. Does that help? whymenotsmart^m^.
