Let g(x)=(x−1)nlog⁡cos⁡m(x−1),0<x<2,mg\left( x \right) = \frac{{{{\left( {x - 1} \right)}^n}}}{{\log {{\cos }^m}\left( {x - 1} \right)}},0 < x < 2,m and nn are integers, m≠0,n>0m \ne 0,n > 0, and let pp be the left hand derivative of ∣x−1∣\left| {x - 1} \right| at x=1x = 1. If lim⁡x→1+g(x)=p\lim\limits_{x \to {1^ + }} g\left( x \right) = p, then
View answer and explanation
Correct option: C
n=2,m=2n = 2,m = 2
Option C (n=2,m=2n = 2,m = 2) is correct because it satisfies the limit condition lim⁡x→1+g(x)=p=−1\lim\limits_{{x \to {1^ + }}} g(x) = p = -1.
