So say we have f (x) = x^2 and we want to evaluate the derivative at point (2, 4). We take the derivative of f (x) to obtain f' (x) = 2x. Afterwards, we just plug the x coordinate of (2,4) into f' (x).Tangents to polar curves. Google Classroom. Consider the polar curve r = 2 cos. ⁡. ( θ) for 0 ≤ θ < π . At which values of θ does the graph of r have a horizontal tangent line? Hi all, here's a score chart for the Calc BC exam (using the 2023 data). The overall exam score is based 71% on AB topics and 29% on BC-only topics, but the subscore is based only on the AB questions. According to this graph, the absolute minimum you need to get correct on the BC exam in order to get a 5 on both is ~64% on AB-level questions ... 9 months ago. Think about the area between curves as the difference between the "higher" function and "lower" function. See that in all the cases shown in the video, f (x) is always greater than g (x). So, the area would be f (x) - g (x). Now, see that after they intersect, g (x) is greater than f (x) and there, the area would be g (x) - f (x).AP Calculus BC solved exams. Unit 12.
