**integration_and_differentiation.mws**. This Maple worksheet introduces you to the basic Maple commands for differentiating and integrating.**newton-raphson.xlsx**. Relates to Example 3.18. This Excel spreadsheet shows how the Newton-Raphson method is used to find square roots.**rect_trap_and_simpson_rule.xlsm**. Relates to the computer code given in Section 6.5. This macro-enabled Excel spreadsheet shows how to integrate numerically using the rectangular rule, the trapezoidal rule and Simpson's rule.

**taylor_series.xlsx**. Relates to Example 9.19. This Excel spreadsheet shows (1) how the Maclaurin series for*e*is accurate only for small^{x}*x*, and (2) how the Maclaurin series for ln(*x*) can be modified to make it accurate to 6 sig. figs for any*x*.

**filtering_by_rlc_circuit.xlsxm**. Relates to Figure 10.33. This Excel spreadsheet uses complex arithmetic to derive these graphs, which describe filtering by an*RLC*circuit.

**fourier_series_for_sawtooth.mws**. Relates to Chapter 10, page 245. This Maple worksheet shows how to use Maple to calculate Fourier coefficients. It shows how to correctly apply symmetry arguments to find the coefficients for the sawtooth waveform.**fourier_transform.xlsm**. Relates to Example 10.14. This Excel spreadsheet calculates the Fourier transform of a wavepacket by doing a whole series of numerical integrations.

**fft.xlsm**. Relates to the computer code in Chapter 10, page 281 and 282 for Example 10.15. This Excel spreadsheet contains a subroutine that does fast Fourier transforms. It is applied to the same wavepacket as the previous spreadsheet.

**fft_of_sunspot_data.xlsm**. Relates to Problem Set 10.3, #6. This spreadsheet is similar to the previous spreadsheet but does an FFT on the historical data for sunspot activity on the sun's surface.
