AB Calculus Ch 11 FRQ Review Differential Equations & Slope Fields Complete these FRQ on your own paper, except for graphing the slope fields. Consider the differential equation 2 1 dy y dx x. (a) On the axes provided, sketch a slope field for the given differential equation at the six points indicated. Mately linearly along a line with slope 3. Area When we first considered integration, we used the definite integral to evaluate area bounded by a curve and the x-axis between two points. If x(t) and y(t) are parametric equations, as with Cartesian Calculus, we can use integration to find the area bounded between them (provided.
