Leaves of polar curves

For a given polar curve, we show, step-by-step, how to find the slope of an arbitrary line and how to find the area of each leaf of the curve.

Tangents to Parametric Equations

We show, step-by-step, how to find the equation of a tangent line to a parametric equation at a given point.

Alternating and Integral Test

We show, step-by-step, how to determine if an alternating series is divergent, conditionally convergent or absolutely convergent.
