Question

Students were asked to simplify the expression (secØ - cosØ)/secØ Two students' work is given.

Student A:
step 1 secØ/secØ - cosØ/secØ
step 2 cosØ/1 - (1/cosØ)
step 3 1 - cos^2Ø
step 4 sin^2Ø

Student B:
step 1 (1/cosØ)-cosØ)/secØ
step 2 (1 - cos^2Ø/cosØ)/secØ
step 3 sin^2Ø/cos^2Ø
step 4 tan^2Ø

Part A: Which student simplified the expression incorrectly? Explain the errors that were made or the formulas that were misused.

Part B: Complete the student's solution correctly, beginning with the location of the error.
