WebThe cosine function is an even function because cos( − θ) = cos θ. For example, consider corresponding inputs π 4 and − π 4. The output of cos(π 4) is the same as the output of cos(− π 4). Thus, See Figure 3. Figure 3 Graph of y = cosθ For all θ in the domain of the sine and cosine functions, respectively, we can state the following: WebIn particular, horizontal and vertical shifts can make an odd function even or an even function odd. For example c o s ( x − π 2) maps cosine to sine. Therefore, c o s ( x − π 2) is odd. Transformations can also make it so that a function is neither odd nor even. The transformation s i n ( x) − 1 is an example. patrignani marcel
