SUMMARY
This discussion focuses on calculating the slope of secant lines using the Desmos graphing tool. The formula for the slope is defined as $m=\dfrac{\delta y}{\delta x}$, where specific points are analyzed, such as P=(0.5, 0) and Q=(x, cos(πx)). The calculated slopes for various values of x include -2 for x=0 and approximately -9.998 for x=0.4. The relevance of derivatives is clarified, emphasizing that the discussion is centered on secant lines rather than tangent lines.
