Periodic Formulas. If n is an integer. sin ( q + 2 p n ) = sin q csc ( q + 2 p n ) = csc q. cos ( q + 2 p n ) = cos q sec ( q + 2 p n ) = sec q. tan ( q + p n ) = tan q cot ( q + p n ) = cot q.
know how cos, sin and tan functions are defined for all real numbers; be able to sketch the graph of certain trigonometric functions; know how to differentiate the cos, sin and tan functions; understand the definition of the inverse function f−1(x) = cos− 1(x).
Period. The period of a function is the number, T, such that f ( θ + T ) = f ( θ ) . So, if ω is a fixed number and θ is any angle we have the following periods. sin → 2 π T = ω ( ωθ ) cos ( ωθ ) → 2 π T = ω. tan ( ωθ ) → π T = ω. csc ( ωθ ) → = 2 π T ω. sec ( ωθ ) → 2 π T = ω.
Periods of the Trig Functions. The period of a function is the number, T, such that f ( +T ) = f ( ) . So, if ! is a xed number and is any angle we have the following periods. 2. sin(! ) ) T = ! 2. cos(! ) ) T = !
