. Finds all critical points. Use the second derivative test to classify the critical points as local maxima or local minima (if the test fails, say so). Find the intervals on which the function is increasing and on which the function is decreasing. . Find the intervals on which the function is concave up and on which the function is concave down. Determine all points of inflection. Using ONLY the information from the previous steps (DO NOT GRAPH ON YOUR CALCULATORI!!), sketch an accurate graph of the function. Be sure to plot all points of inflection as well as local maximums and local minimums. 1. F(x)- cosA2 (x) (its cos squared x, not cos squared multiplied by x)
