Answer 1

Summary: The given .vi (virtual instrument) plots a sine wave and cos wave over a single cycle having period N=100 on the same graph indicator. The analytical expression for the sine wave produced is sin(2*pi*n/100) and the expression for cos wave is cos(2*pi*n/100). The number of samples (n) taken in single cycle for both waves are 101 which is the loop count. The build array at the output of the loop is used to plot the both array signals in the same graph.

4) The constant 100 inside the loop is specifying the fundamental period (N) of both the waves as given in the equations. The for loop count 101 specifies the number of samples which is indicated by (n). If the 'n' is increased for same N, more number of cycles are plotted.
