This problems covers on the topics related to trigonometric function , some of the topics are range, graph of the function, determine periodic or not etc.,1. The range of the graph of y=cosxis2. Which statement is not true about the graph off(_)=cot_3. The graph shown is of the function4. The functions have vertical asymptotes at_=n_/2where n is an odd integer.The functions do not have a y-interceptThe functions have zeroes atThe functions have a maximum value
