What are the points of inflection of #f(x)= 3sin2x - 2xcosx# on #x in [0, 2pi] #?
1 Answer
x
Explanation:
Begin by finding the first and second derivatives
Next go ahead and set
Looking at the graphs of
graph{3sin(2x)-2xcos(x) [0, 6.2831853071795864769, -5, 5]}
graph{ 2xsin(x)+6cos(2x)-2cos(x) [0, 6.2831853071795864769, -5, 5]}
graph{2xcos(x) + 4sin(x) - 12sin(2x) [0,6.2831853071795864769, -5, 5]}
For x
