103 the six circular functions and fundamental identities 745 the word ‘tangent’ comes from the latin meaning ‘to touch,’ and for this reason, the line x= 1. Another thing to notice is the symmetry of the sine and cosine functions the sine function is an odd function recall this means that if (x,y) is on the graph of the function so too is the point (-x,-y. Some rules and tips for proof questions: 1) start with one side, usually the more complex one 2) use known (basic) trig identities. In this lesson you will view the trigonometric ratios of angles of rotation around the coordinate grid as a continuous, circular function the connection will be made between how the ratios change as the angle of rotation increases or decreases, and how the graph of the function depicts that change.
Circular functions are part of the set of trigonometric functions whereas trigonometric functions consist of domains that are sets of angles and ranges that are real numbers, circular functions have domains that are sets of numbers that correspond to the angles of the trigonometric functions (in radians.
