Question: Consider the functions f and g, where f (x) = 6 sin x cos 2 x and g(t) = t 0 f (x) dx.(a)

Consider the functions f and g, where f (x) = 6 sin x cos2 x and g(t) = ∫t0 f (x) dx.(a) Use a graphing utility to graph f and g in the same viewing window.(b) Explain why g is nonnegative.(c) Identify the points on the graph of g that correspond to the extrema of f.(d) Does each of the zeros of f correspond to an extremum of g? Explain.(e) Consider the function


- SP1 /2 h(t) = f(x) dx.


Use a graphing utility to graph h. What is the relationship between g and h? Verify your conjecture.

- SP1 /2 h(t) = f(x) dx.
