FAQs on RS Aggarwal Class 11 Solutions Chapter 27 Limits
1. Find the Value of the Positive Integer “n” so that limx → 3((xn– 3n)/(x – 3))b = 108.
Given that,
limx → 3((xn– 3n)/(x – 3))= 108
Now, we have:
limx → 3((xn– 3n)/(x-3))= n(3)n-1
n(3)n-1 = 108
Now, this can be also written as:
n(3)n-1 = 4 (27) = 4(3)4-1
Therefore, from the rule of exponents, by comparing the exponents in the above equation, we get:
n = 4
Therefore, the value of the positive integer “n” is 4.
2. Let f(x) = x2 – 4. Now, Compute limx→2f(x).
If , limx→2f(x) = limx→2x2–4
=> 22 – 4 = 4 – 4 = 0
Hence the value is zero.
3. Evaluate limx→2((x2-4)/(x-2)).
It is given that,
limx→2((x2-4)/(x-2)) = limx→2((x+2)(x-2)/(x-2))
We can cancel the term (x-2) from numerator and denominator. Because the value may not change if the cancellation has happened in both the numerator and the denominator.
Then we can get,
limx→2 x+2 = 2+2 = 4
Hence the value is 4.
4. Solve limx→2 (sin 2x/x)
Given that,
limx→2 (sin 2x/x)
We can write it as;
limx→2 (sin 2x/2x) × 2
By multiplying the two on both sides, we will get,
Also, we know that limx→2 (sin x/x)= 1
Therefore,
limx→2 (sin 2x/2x) × 2 = 1 × 2 = 2
Hence the answer is 2.
