sinx-1 evaluates to s-1
tanx+secx evaluates to t+sHere, you are trying to multiply two binomials together. To work this problem, we'll use the "F.O.I.L." method. First, we'll multiply the two First terms, the s and t together. Second, we'll multiply the two Outer terms, the s and s together. Third, we'll multiply the two Inner terms, the -1 and t together. Lastly, we'll multiply the two Last terms, the -1 and s together. The correct answer is st + s^2 - t - sThank you for posting your question. I hope that this answer helped you. Let me know if you need more help.
