I was giving a test last year and wrote three different versions of the test. The problem was an indefinite integral of the form S f (x)dx . I found the copies of their tests in my filing cabinet, but the paper had yellowed and I couldn't read the equation for the integrand f(x). I can't tell you their names because I don't want to violate FERPA laws. Student A wrote the answer sin? (x) + C. Student B wrote the answer – cos?(x) + C. Student C wrote the answer – sin? (x) + C. According to my marks on the test, two of the students answered the question correctly. What was the original question? Who got the answer wrong? Justify your answers.
