C

send me the solution also.

pics not upload due to network problem plz wait

check solution

sir, please explain the Lagrange point wala part

langrange point means point where condition satisfy

since x² is always positive we calculate those angle where x²>0

what's ur dabut

sir my doubt is that in this question there exists atleast one rolle's point , so why we take lagranges point?

roll point is also langrangee point

in langrange th f'(c)=f(b)-f(a)/b-a. if f(a)= f(b) then f'(c) = 0

understood or not

ok sir.
