Answers
Answer:
x² will be the perfect answer of this question.
Answer:
The first two terms in the expansion of in ascending powers of (x - 2) will be and e(x-2)
Step-by-step explanation:
We will use Taylor's Theorem to solve this question.
According to Taylor's Theorem, for a function f(x), in ascending powers of (x-a)
f(x) = f(a) + f'(a)*(x - a) + f''(a) * + . . . . . . . . . + fⁿ⁺¹(a) *
where, f'(a) = First derivative
f''(a) = Second derivative
and so on
Here, in this question, f(x) = and a = 2 ;
=>f(a) =
Therefore, f'(x) = f'(1) = e
f''(x) = f''(1) = e
Since we need the first two terms,
=> = + e * (x-2)
=> = + e(x-2)
Therefore, the first two terms in the expansion of in ascending powers of (x - 2) will be and e(x-2)
