find and .Given the function f(x)=ln(3+sinx) on the interval [0,7]
a. at which values of x does f have local max and local min
To find the critical points, set and solve for (only take the values between 0 and 7 inclusive.
To find whether the point you found above are max's or min's, check the following:
If then we have a local max
If then we have a local min
