Use a graphing utility to complete the table and graph the functions in the same viewing window. Use both the table and the graph as evidence that y1 y2. (Round your answers to four decim Y = cos(x) + sin(x) tan(x), y2 = sec(x) x Y Y2 4.3 Verify the identity algebraically. 4.8 5.3 5.8 Y = cos(x) + sin(x) tan(x) = cos(x) + cos(x) cos(x) 6.3 6.8 7.3
