Find the absolute max and min of f(x)= e^-x sin(x) on the interval [0, 2pi]

Find the absolute max and min of f(x)= (x^2) / (x^3 +1) when x is greater or equal to 0

Solutions

Expert Solution

For the 1st solution; you can put the value of e.

For 2nd question; infinity is an range. But you can not find f(infinity) as infinity is not real number and you will find lim (x tend to infinity) f(x) and look that for our problem it is nither max nor min. Remember that always question is set in the way that infinity will not be a point of max or min.

If you have any problem to understan my solution please comment. I will explain. Thank you
