Question

Tentukan limit dari satu soal dibawah ini

Answer 1

U = (2u+1)2- 9          v = u2+2u-3
u' = 2(2)(2u+1)          v' = 2u+ 2
   = 4(2u+1)
   = 8u + 4
y= u/v= u'v-v'u/v2
 = (8u+4)(u2+2u-3) - (2u+2) (2u+1)2-9 / (u2+2u-3)2
=8u3 + 20u2 -16u -12 -(2u+2)(2u+1)2 - 9 / (u2+2u-3)2
= 8u3 +20u2 -16u-21-(2u+2)(2u+1)2/(u2+2u-3)2
