 * Equation of function: **f(x) = cos (x) ** **

 
 * Domain: (-infinity, +infinity), all real numbers **
 * Range: [-1,1] **
 * Discontinuities: None **
 * Symmetry: About the y-axis **
 * Even, odd, or neither: - cos(-x)cos(x) ->Even**
 * End behavior using limits:** **lim x → 0 cos(x) = cos(0) = 1**
