Practice Exam for the first Midterm (Time: 90 minutes) 1. Evaluate the following integrals: (a) x 3 + 1 x dx (b) π 8 0 e 2 x + 3 cos (2 x ) dx ( Remark : your final answer may not contain any sin or cos-function.) 2. The power which a power station is providing during a 24 hour period to a city is given by the function f ( t ) = 200 + 100 sin 2 πt 24 . (The time is measured in hours after midnight, the power is measured in megawatts. Power is the rate of change in the energy produced by the power plant.) Answer the following questions: (a) For the the term 100 sin 2 πt 24 , what is the amplitude, the period, and the frequency? (b) When is the energy output of the plant greatest and when lowest? (c) What is the average power output between midnight and noon? (d) What is the average power output during the whole day? 3. If F ( x ) = x 3 - 1 and F (1) = 2 what is

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
