- Students were asked to simplify the expression (secØ - cosØ)/secØ Two students' work is given.Student A: step 1 secØ/secØ - cosØ/secØstep 2 cosØ/1 - (1/cosØ)step 3 1 - cos^2Østep 4 sin^2ØStudent B: step 1 (1/cosØ)-cosØ)/secØstep 2 (1 - cos^2Ø/cosØ)/secØstep 3 sin^2Ø/cos^2Østep 4 tan^2ØPart 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.arrow_forwardAlthough 330° is a special angle on the unit circle, Amar wanted to determine its coordinates using the sum and difference formulas.Part A: Determine cos 330° using the cosine sum identity. Be sure to include all necessary work.Part B: Determine sin 330° using the sine difference identity. Be sure to include all necessary work.arrow_forwardA public health researcher is studying the impacts of nudge marketing techniques on shoppers vegetablesarrow_forward
- 4. Let A {w, e, s, t, f, i, e, l, d, s, t, a, t, e}. (a) How many different words (they do not have to make sense) can you spell with the letters in A? (b) Is your answer from above the same as the cardinality of the powerset of A, i.e. of P(A)? (c) What is |A|?arrow_forwardwhat can the answer be pls helparrow_forward5. How many numbers can you make out of the digits 1, 2, 3, 4, 6 if the rule is that every digit has to be larger than the digit preceding it? For example 124 is ok, 122 is not ok. Every digit can be used only once, but you do not have to use every digit. A tree might help.arrow_forward
