MORE ABOUT CONTINUOUS FUNCTIONS

You will learn to solve more problems on continuous functions and find the parameters when the functions are continuous.

Problems are solved for you to learn and practice.

HOW TO FIND K, IF f IS CONTINUOUS AT 0

CONTINUITY AT A POINT

Discuss the continuity of Modulus of x. If f(x)= x^3 +3 , if x is not equal to 0, f(x) = 1,when x = 0, discuss the continuity of f at x = 0. If f(x) = x, if x is lesser than or equal to 1, f(x) = 5, if x is greater than 1, discuss the continuity of f at x = 1. If f (x ) = k x ^2, if x is lesser than or equal to 2, f(x) = 3, if x is greater than 2, Find k, if f is continuous at x = 2. Watch all this and more ! Here, you will learn how to check if a function is continuous at a point. It is an integral part of Class 12 Mathematics. You will be introduced to Continuity at a point, left hand and right hand limits for Continuity. Have you ever wanted to be introduced to Calculus. This video will lead you into the basic fundamentals of Calculus. You will learn about continuous functions, left hand limits, right hand limits and continuity at a point. A very useful video for ISC and CBSE students of class 12. Online tutoring is provided for further help. You could register for a masterclass or the entire course.

Being a mathematics educator for close to three decades, I hope to make math easy for you through these lessons. This lesson prepares you to handle differentiation of logarithmic functions and higher order differentiation in general. Not to mention, it would greatly help students of class 12 l, ISC and CBSE boards who are learning mathematics.

PARAMETRIC DIFFERENTIATION EXPLAINED-12TH MATHS NCERT -QUESTION WITH SOLUTION

SECOND ORDER DERIVATIVES

Here, you will be introduced to problems on Second Order Derivatives. Rolle's Theorem and its geometrical application is also introduced. In Class 12 Mathematics, you are generally asked to solve a lot of identities in Differentiation , involving second order derivatives. This lesson prepares you for this. There is also the statement of Rolle's Theorem with its geometrical implication which is introduced. This lesson is aligned with the class 12 syllabus which only focuses on application of Rolle's Theorem. Hence, the proof of Rolle's Theorem is not mentioned. I am a math educator teaching mathematics for over two decades. I have tried to simplify this topic for you. This lesson is a good takeaway for Class 12 students of the ISC, CBSE or any other board.

DERIVATIVE AS A RATE MEASURE

Learn how you can calculate derivative as a rate measure in this video. You will learn how to apply derivatives in real life situations. You will use geometry and derivatives to calculate how to find the rate of change in the derivative. Being a math educator for close to three decades, I have tried to simplify this for you in this video. This topic is slightly tricky as you need to understand the problem first

MORE PROBLEMS ON DERIVATIVE AS A RATE MEASURE

Here, you will learn how to work out problems using derivative as a rate measure. You will learn how to calculate the rate of change of the variables in each problem. We touch upon problems in Geometry like a cone and sphere. Some of the problems discusses include: If an edge of a cube is increasing at a certain rate, at what rate is the volume increasing? If a girl of a certain height walks away from a lamppost, how much is the length of her shadow increasing? Online classes are also provided. You can choose between specific topics or the entire course. MCQS and case study questions are also included. You can contact me on mathmadeeasy22@gmail.com
