Question
Let y = x3 - 8x + 7 and x = f(t). If 
= 2 and x = 3 at t = 0, then 
at t = 0 is given by
= 2 and x = 3 at t = 0, then at t = 0 is given by Options
A.1
B.19/2
C.2/19
D.none of these
Solution
y = x3 - 8x + 7 and x = f(t)
= 2 & x = 3 at t = 0
∵
⇒ 
⇒
∵ at t = 0, x = 3
∴
(at t = 0) = 
= 2 & x = 3 at t = 0∵
⇒ ⇒
∵ at t = 0, x = 3
∴
(at t = 0) = Create a free account to view solution
