Question 2a in 2009 Exam 1
a. Find an anti-derivative of 1/1-2x with respect to x. The solution does not include c as real constant.

Question 2a in 2010 Exam 1
a. Find an antiderivative of cos(2x + 1) with respect to x.. The solution includes c as real constant.

Is c necessary?
Thanks

For 'an', no it isn't necessary.

The 2010 assessor report also says "where c is a real constant (but not necessary)"

If it says "the" antiderivative, you need the +c.

For "an" antiderivative, you don't have to include +c. You can add 5922 if you wanted...
