The document contains definitions and graphs of trigonometric functions including sine, cosine, tangent, cotangent, secant and cosecant over the domain of 0 to 2π or 6π. For each function, it lists key characteristics such as the domain, range, intercepts, asymptotes, maximum and minimum points. It also discusses the monotonicity of the cosine function over intervals from 0 to π and π to 2π.
