Chain Rule is one of the most important concepts in Differentiations That's why we will discuss it in upcoming concepts till then you can take some basic idea of this concept Thanking You !!
Case 1 :                  Case 2 :                =>    correct option (2)     Option 1) Option 2) Option 3) Option 4)
has exterme points at  So,  at    we can write   given that                                                Option 1) four irrational numbers. Option 2) four rational numbers. Option 3) two irrational and two rational numbers. Option 4) two irrational and one rational number.
Find shortest distance   the tangent at point P is parallel to So putiing the value of in curve                                              Shortest distance between two parallel lines or perpendicular distance from       Option 1) Option 2) Option 3)   Option 4)
Indeterminate forms - The form   are known as indeterminate form means they do not exist directly -     L - Hospital Rule - - wherein Given  and    This is in the form of L.D.E I.F. =        =  Now, So,  Option 1)exists and equals 0Option 2)does not existOption 3)exist and equals Option 4)exists and equals 4

As we have learned Properties of differentiable functions - The composition of a differentiable function is a differentiable functions. -      is composition of sin x with sin x so it will  be diffrentiable      is compostion of  with  (both diffrentiable ) so it will be also diffrentiable    so sum of two diffrentiable function will also be diffrentiable for all            Option 1) 0 Option...

As we have learned Irremovable discontinuity - A function f is said to possess irremovable discontinuity if at  x = a the left hand limit is not equal to the right hand limit so limit does not exist   -     Limit doesn't exist  , f(x) has irremovable discontinuty , so ffor no 'k' it will be continous     Option 1) If k= 1 , f(x ) becomes continous at x= 0 Option 2) If k= -1 , f(x ) becomes...

As we learnt in Condition for differentiable - A function  f(x) is said to be differentiable at    if      both exist and are equal otherwise non differentiable -      and      So f(x) is continuous at x = 0   So, g(x) is differentiable at        Option 1)  Both statements I and II are false.     This option is incorrect. Option 2)  Both statements I and II are true. This option is...
