Feb 9, 2023 · In the formulas given here, you have: r (radius); d (diameter or distance); b (base or measure of a side); h (height); a, b, c (measures of sides); x, y (coordinates on a graph); m (slope); M (midpoint); h, k (horizontal and vertical distances from the center); θ (angle theta); and s (arc length). The formulas particular to trigonometry have ...
The period of a function is the number, T , such that f ( + T ) = f ( ). So, if ! is a fixed number and is any angle we have the following periods. sin (! ) ! 2 T = ! cos (! ) ! 2 T = ! tan (!
) = cos( ) cos( ) − sin( ) sin( ) − ) = cos( ) cos( ) + sin( ) sin( )
