(x+1) ^2. So for this problem i learned the X factory in order to solve it. so what u. need to do is find a number(s) that multiply to 1. (the one on the far right is the one u multiply) and a those same numbers need to add to 2. so one and one multiply to one and add up to 2. so u do (x+1) (x+1) but since there the exact same u just put a little 2 up on the brackets
Answer:
•cos(s+t) = cos(s)cos(t) - sin(s)sin(t) = (-⅖).(-⅗) - (√21 /5).(⅘) = +6/25 - 4√21 /25 = (6-4√21)/25
•cos(s-t) = cos(s)cos(t) + sin(s)sin(t) = (-⅖).(-⅗) + (√21 /5).(⅘) = +6/25 + 4√21 /25 = (6+4√21)/25
cos(t) = ±√(1 - sin²(t)) → -√(1 - sin²(t)) = -√(1 - (⅘)²) = -⅗
sin(s) = ±√(1 - cos²(s)) → +√(1- cos²(s)) = +√(1 - (-⅖)²) = √21 /5
