This video lecture covered what is continuity.
Explained that a curve is called continuous if  we can draw a curve without picking up a pen.

What is condition of continuity at a point x=a.
Explained that curve is called continuous at x=a  if right hand limit is equal to left hand limit is equal to  f(a) and all are finite.

Also explained geometrically that if we move RHL to LHL or LHL to RHL at x=a without picking up a pen than curve is called continuous at x=a.
Also explained that  f is continuous at x=a implies limit exist at x=a but converse is not true.

How to check continuity at extreme point in closed interval also explained.
Which function is called continuous function also discussed.

Continuity of trigonometric function discussed in very detailed manner.
Explained why trigonometric functions are continuous in their domain with the help of their graphs.
Inverse trigonometric functions continuity also discussed with the help of their graphs.

Explained why logarithmic functions are continuous in their domain.
Also explained continuity of exponential functions.

Why greatest integer functions are not continuous at integers also explained.
Fractional part discontinuity behavior at integers also explained.

why signum function is not continuous at x=0 also discussed.
