Task 2(20 points) Consider the function f(x)=sin2(x).(a) Determine where f(x)is strictly increasing and where f(x)is strictly decreasing in theinterval 0,2.(b) Determine where all of the local maximums and local minimums off(x)(if any) occur onthe interval 0,2. i understanding the exercise but what you use to find the critical points ? like which programme used as maple wordmat or somthing like that can you explained how can use maple or word mat to finde critical point ?
