Here is the table related to the topics in ML Aggarwal Class 12 Solutions:

Question 1:
What is the fundamental principle of differentiation?

Answer:
The fundamental principle of differentiation is based on the limit definition of a derivative, which describes how a function changes as its input changes. It measures the rate of change of a function with respect to the variable.

Question 2:
Explain the method of integration by parts.

Answer:
The method of integration by parts is derived from the product rule of differentiation. It is used to integrate products of two functions by transforming the integral into a simpler form.

Question 3:
What is the concept of continuity in a function?

Answer:
Continuity of a function means that the function does not have any breaks, jumps, or holes in its graph. For a function to be continuous at a point, three conditions must be satisfied: the function must be defined at the point, the limit must exist, and the value of the function must be equal to the limit.

Question 4:
What is the difference between a sequence and a series?

Answer:
A sequence is a list of numbers arranged in a particular order, while a series is the sum of the terms of a sequence. A series is formed by adding each term in the sequence.

Question 5:
What is the derivative of sin(x)?

Answer:
The derivative of sin(x) with respect to x is cos(x). This is one of the standard results in differentiation.

Question 6:
How do you find the area under a curve using integration?

Answer:
To find the area under a curve, you integrate the function with respect to the x-axis between the given limits. The integral gives the area enclosed by the curve and the x-axis.

Question 7:
Explain the concept of a limit in calculus.

Answer:
A limit is the value that a function approaches as the input approaches a certain value. It is fundamental in calculus, especially in defining derivatives and integrals.

Question 8:
What is an irrational number? Give an example.

Answer:
An irrational number is a number that cannot be expressed as a ratio of two integers. It has a non-terminating, non-repeating decimal expansion. An example is π (pi).

Question 9:
What is the importance of solving quadratic equations?

Answer:
Solving quadratic equations is essential because they represent various real-world problems, such as projectile motion, optimization, and more. Quadratic equations are fundamental in algebra.

Question 10:
What is a probability density function?

Answer:
A probability density function (PDF) is a function that describes the likelihood of a continuous random variable taking on a particular value. The area under the curve of a PDF represents the probability of the variable falling within a given range.

Question 11:
How do you differentiate a composite function?

Answer:
To differentiate a composite function, you apply the chain rule. The chain rule states that the derivative of a composite function is the derivative of the outer function multiplied by the derivative of the inner function.

Question 12:
What is the relationship between differentiation and integration?

Answer:
Differentiation and integration are inverse operations. Differentiation breaks down a function into its rate of change, while integration finds the accumulated area or the original function from its rate of change.

Question 13:
Explain the concept of a conic section.

Answer:
A conic section is the curve formed by the intersection of a plane and a cone. The four main types of conic sections are the circle, ellipse, parabola, and hyperbola.

Question 14:
What is the equation of a straight line?

Answer:
The equation of a straight line in slope-intercept form is y = mx + c, where m is the slope of the line and c is the y-intercept.

Question 15:
What is the principle of mathematical induction?

Answer:
Mathematical induction is a method of proving that a statement is true for all natural numbers. It involves proving the base case and then showing that if the statement is true for an arbitrary case, it is also true for the next case.

Question 16:
What is the value of the determinant of a 2x2 matrix?

Answer:
The determinant of a 2x2 matrix is calculated as the difference between the product of the elements on the main diagonal and the product of the elements on the other diagonal. For matrix A = [a, b; c, d], the determinant is ad - bc.

Question 17:
What is a binomial expansion?

Answer:
A binomial expansion is the expansion of an expression raised to a power, such as (a + b)^n. The expansion uses the binomial theorem to express the powers as a sum of terms involving binomial coefficients.

Question 18:
What is the inverse of a matrix?

Answer:
The inverse of a matrix is another matrix that, when multiplied by the original matrix, yields the identity matrix. Not all matrices have an inverse; a matrix must be square and have a non-zero determinant.

Question 19:
What is the concept of eigenvalues and eigenvectors?

Answer:
Eigenvalues and eigenvectors are used in linear algebra. An eigenvalue is a scalar that indicates how much a matrix stretches or compresses space, while an eigenvector is a vector that only changes in magnitude, not direction, when a matrix is applied to it.

Question 20:
What is a function in mathematics?

Answer:
A function is a relation that associates each element of one set (the domain) with exactly one element of another set (the range). Functions are fundamental concepts in mathematics and are used to describe relationships between quantities.
