Answer» While solving this question we have APPLIED L' hospital rule wherever we are getting 0/0 form. In this we have to differentiate NUMERATOR and denominator seperately. Additional-Information :-While applying L' hospital rule we have to differentiate. To differentiate we must know basic differentiation formulae :- d(e^x)/dx = e^x d(x^n)/dx = n x^(n-1) d(LN x)/dx = 1/x d(sin x)/dx = cos x d(cos x)/dx = - sin x d(tan x)/dx = sec² x d(sec x)/dx = tan x * sec x d(cot x)/dx = - cosec²x d(cosec x)/dx = - cosec x * cot x |
