I made this one, and it was copied from my unfinished work.

y2-x2= 1。 8.& gt2.9.8. 10. 10

17.s= 100Q+200cosQ

SinQ= 1/2

18.( 1)x2/4+y2/3= 1

(2)48/7 & lt; = a b+ CD & lt; =7

20.an=Bn- 1-bn.... 1

1/bn-1/bn-1=1/2an ... 2 from1/bn = (TN+1)/2 = (TN-/kloc-0

2q 2-5q+2 = 0q = bn/bn- 1 When the generation of 1 advances to 2.

Q= 1/2 or q=2 (s).

B 1= 1, so the common ratio of bn is 1 and the equal ratio is 1/2.

The last question is to do or not to do.

Please adopt it.
