Given values :

The function f(x) = x is continuous at x = 0.

To Prove :

That the function f(x)=x is continuous at x=0, but not differentiable at

x = 0.

Solution :

First of all prove :

We know that :

Note :

If this is required then use!

Then,

So,

Now,

To Represent :

So,

Did you observe?

So, You should obesreve! that,

The limit from the right is 1 while the limit from the left is - 1.

Hence,

The two sided limit does not exist.

That is, the derivative does not exist at x = 0

What is rolle's theorem?

Posted by Kanishk Gupta 5 years, 3 months ago

CBSE > Class 12 > Mathematics

1 answers

Meghna Thapar 5 years, 3 months ago

Rolle's theorem states that if a function f is continuous on the closed interval [a, b] and differentiable on the open interval (a, b) such that f(a) = f(b), then f′(x) = 0 for some x with a ≤ x ≤ b.

All 3 conditions of Rolle's theorem are necessary for the theorem to be true:

f(x) is continuous on the closed interval [a,b];
f(x) is differentiable on the open interval (a,b);
f(a)=f(b).
The conclusion of Rolle’s theorem is that if the curve is continuous between two points x = a and x = b, a tangent can be drawn at each and every point between x = a and x = b and functional values at x =a and x = b are equal, then there must be atleast one point between the two points x = a and x = b at which the tangent to the curve is parallel to the x-axis.

Just as definite integrals can be used to find the area under a curve, they can also be used to find the area between two curves. To find the area between two curves defined by functions, integrate the difference of the functions. ... In this section, we use definite integrals to find volumes of three-dimensional solids.

Khushi....? ??‍? 5 years, 3 months ago

In calculus, integration by substitution, also known as u-substitution or change of variables, is a method for evaluating integrals. Direct application of the fundamental theorem of calculus to find an antiderivative can be quite difficult, and integration by substitution can help simplify that task.
