x =4- t2 Curve C is defined parametrically by : ;0st -2 t ( This is the same curve as was given in HW #5. ) 1. Determine the slope of the tangent line to the curve at t = 2 using the formula : dy | at mtan = dx at2. Compute the area enclosed by the curve in Quadrant I be setting up and evaluating a parametric integral ; use a horizontal representative rectangle, and start with a formula for dA
