i was checking my work and I realized like seconds before time ran out

1. k=3
2. 0.314 3sf
   3)x=0.5ln(sqrt(5)-2) and x=0.5sqrt(0.5(sqrt(5)1-1)
   4)-x+1.5x^2-4/3x^3+25/12x^4
   5)arcsin(2.5sqrt(2)x) +c and arccosh(0.5x-1.5) +c
   6)trivial (PBI)
   7)9,10,3
   8)0.5-2sqrt(2)
   9)19.4%

Could have written it wrong or forgotten it a bit this is all I remember
