Two students wrote antiderivative formulas for k sin (kx), where k > 1.

Student 1: Integral of (k sin (k x) ) d x = k squared cosine (k x) + C

Student 2: Integral of (k sine (k x) ) d x = negative cosine (k x) + C

Which student, if any, wrote a correct antiderivative formula?

Student 1 only

Student 2 only

both Student 1 and Student 2

neither Student 1 nor Student 2
