In y cos x the center is the x axis and the amplitude is 1 or A 1 so the highest and lowest points the graph reaches are 1 and 1 the range of cos x Compared to y cos x shown in purple below the function y 2 cos x red has an amplitude that is twice that of the original cosine graph Cofunction Identities in Degrees The co function or periodic identities can also be represented in degrees as sin 90 x cos x cos 90 x sin x tan 90 x cot x cot 90 x tan x sec 90 x cosec x cosec 90 x sec x

Free math problem solver answers your trigonometry homework questions with step by step explanations The basic sine and cosine functions have a period of 2 pi The function sin x is odd so its graph is symmetric about the origin The function cos x is even so its graph is symmetric about the y axis The graph of a sinusoidal function has the same general shape as a sine or cosine function
