APFIVE Slope of a Polar Curve
The formula for the slope dy/dx of a polar curve requires computing the derivatives of y = r sin θ and x = r cos θ with respect to θ. What is the justification for this procedure?
A
To isolate the effects of r and θ on the Cartesian coordinates
B
To apply the chain rule separately to the y and x components of the polar function
C
To separate the tangential and normal components of the curve’s motion
D
To account for the radial and angular velocities independently
