(b) \( k^{-1}\cdot e \)
(c) \( ke^{-1} \)
(d) \( k^{-1}\cdot e^{-1} \)
Show Answer & Explanation
Answer: (d) \( k^{-1}\cdot e^{-1} \)
Explanation:
1. Let L be the limit: \( \ln L=\lim\frac1n\sum_{r=1}^n\ln\frac{r}{kn}=\int_0^1\ln\frac xkdx=\int_0^1\ln x\,dx-\ln k=-1-\ln k \).
2. So L = 1/(ke).

(a) \( 2^k \)
(b) \( \frac{2^k}{k+1} \)
(c) \( \frac1{k+1} \)
(d) none of these
Show Answer & Explanation
Answer: (b) \( \frac{2^k}{k+1} \)
Explanation:
1. The numerator is \( 2^k\sum r^k \), so the expression is \( 2^k\cdot\frac1n\sum\left(\frac rn\right)^k \).
2. The limit is \( 2^k\int_0^1x^kdx=\frac{2^k}{k+1} \).

(b) g(x) − g(π)
(c) g(x) g(π)
(d) g(x)/g(π)
Show Answer & Explanation
Answer: (a) g(x) + g(π)
Explanation:
1. \( g(x+\pi)=g(\pi)+\int_\pi^{x+\pi}\cos^4t\,dt \).
2. Since cos⁴t has period π, the last integral equals g(x). So g(x + π) = g(x) + g(π).

(c) \( \frac{(5-\log2)a+\frac72b}{a^2-b^2} \)
(d) none of these
Show Answer & Explanation
Answer: (b) \( \frac{(\log2-5)a+\frac72b}{a^2-b^2} \)
Explanation:
1. Replace x by 1/x: \( af(1/x)+bf(x)=x-5 \). Eliminating f(1/x): \( (a^2-b^2)f(x)=a\left(\frac1x-5\right)-b(x-5) \).
2. Integrate from 1 to 2: \( \int_1^2\left(\frac1x-5\right)dx=\ln2-5 \) and \( \int_1^2(x-5)dx=-\frac72 \).
3. So the integral is \( \frac{a(\ln2-5)+\frac72b}{a^2-b^2} \).

Answer: (c) HP
Explanation:
1. \( a_{n+1}-a_n=\int_0^{\pi/2}\frac{\sin^2(n+1)x-\sin^2nx}{\sin x}dx=\int_0^{\pi/2}\sin(2n+1)x\,dx=\frac1{2n+1} \) (using sin²A − sin²B = sin(A + B) sin(A − B)).
2. The differences are 1/3, 1/5, 1/7, ..., whose reciprocals 3, 5, 7, ... are in AP, so the differences are in HP.
