Answer:

Hindi chapter 14 class 8 Short summary

Explanation:

अन्नपूर्णानन्द वर्मा जी की कहानी “अकबरी लोटा” एक रोचक मगर हास्य पूर्ण कहानी है । अकबरी लोटा कहानी का ताना-बाना लेखक ने कुछ इस शानदार अंदाज में बुना है कि पाठक की रूचि कहानी के अन्त तक बनी रहती है।

संक्षेप में कहानी बस इतनी सी है कि एक दोस्त ने अपनी “सच्ची मित्रता का धर्म” निभाने का पूरा पूरा प्रयास किया। जिसके लिए उन्होंने थोड़ा झूठ का सहारा भी लिया। उन्होंने एक बेकार व बेढंगे से लोटे को “ऐतिहासिक अकबरी लोटा” बताकर एक अंग्रेज अधिकारी को मूर्ख बनाया और फिर उसे अच्छे खासे दामों में उस अंग्रेज अधिकारी को ही बेच दिया। जिससे उनके दोस्त की आर्थिक समस्या भी हल हो गई और अंग्रेज अधिकारी भी खुश हो गया।

Answer:

Rolle’s theorem states that if a function f is continuous on the closed interval [a, b] and differentiable on the open interval (a, b) such that f(a) = f(b), then f′(x) = 0 for some x with a ≤ x ≤ b. In other words, if a continuous curve passes through the same y-value (such as the x-axis) twice and has a unique tangent line (derivative) at every point of the interval, then somewhere between the endpoints it has a tangent parallel to the x-axis. The theorem was proved in 1691 by the French mathematician Michel Rolle, though it was stated without a modern formal proof in the 12th century by the Indian mathematician Bhaskara II. Other than being useful in proving the mean-value theorem, Rolle’s theorem is seldom used, since it establishes only the existence of a solution and not its value
