Explain why the slope of the line tangent to the polar graph of r = f(?) is not dr/d?.

Solution 3EStep 1:In this problem we need to explain why the slope of the line tangent to the polar graph of r = f(is not .The derivative of polar function function r(is .Let us consider , r = 2cos(.The derivative of polar function function r(is .In this case it is = - 2sin(.If you plot r( on the way that ‘ is on the horizontal axis and ‘r’ is on the vertical axis , you get...
