OddEven Property Proof: Recall that y = f(x) is a vertical reflection of y = f(x) across the x-axis and that y = f(x) is a horizontal reflection across the y-axis. a. Figure 5-3e shows y = sin x. Sketch the graph resulting from a reflection of y = sin x across the y-axis, and sketch another graph resulting from a reflection of y = sinx across the x-axis. Based on the results, explain why the sine is an odd function. b. Figure 5-3f shows y = cos x. Sketch the graph resulting from a reflection of y = cos x across the y-axis. From the result, explain why cosine is an even function.
