To think about the concept of "slope at a point" along a curve
To look at lines tangent to curves and to relate them to "slope at a point"
To consider how we might calculate the slope of a line tangent to a curve
This lesson discusses lines tangent to curves and ponders how we might calculate the slopes ofthese lines.
This video looks at the slope of lines tangent to arbitrary functions at different points, and begins considering how these slopes might be found.
We demonstrate how we can thinking the slope of the tangent line as a limit of secant lines.
