SUMMARY
The limit of the function y = 1/2(sin x - cos x + e^(π - x)) as x approaches infinity does not exist (DNE) due to the oscillatory nature of the sine and cosine functions. As x increases, the exponential term e^(π - x) approaches zero, rendering it insignificant in the limit evaluation. Therefore, the dominant terms are sin x and cos x, which oscillate indefinitely, confirming that the limit cannot be expressed in terms of a finite value.
