SUMMARY
A Fourier sine series cannot approximate even functions, such as cos(x) or x², due to the nature of the sine function being odd. The sine coefficients for even functions are zero, as the product of an even function and an odd function results in an odd function. Therefore, when applying the Fourier sine series, the calculation for the sine coefficients yields zero, rendering it ineffective for modeling purely even functions.
