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
