Thank you please help!

tan(9) A curve in the xy-plane is determined by the polar equation 1' = 005(9) . a) [3 points] What are the (w, y) coordinates at 9 = f? b) [12 points] Find the equation of tangent line at 9 = %. Hint: For the tangent line you will need to know the slope. Another tip: Try changing the polar equation to cartesian equation if it helps
