Mathematics

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

Answer: The derivative of sin(x) is cos(x).

Question: Define the term ‘Eigenvalue’ in linear algebra.

Answer: An Eigenvalue is a scalar associated with a linear transformation that satisfies the equation $A\mathbf{v}=\lambda \mathbf{v}$.

Question: What is the general solution of the differential equation dydx=y\frac{dy}{dx} = ydxdy​=y?

Answer: The general solution is y=Cexy = Ce^xy=Cex, where $C$ is a constant.

Question: What is the integral of $1/x$?

Answer: The integral of $1/x$ is $\ln |x|+C$.

Question: Define the term ‘Vector Space’.

Answer: A vector space is a set of vectors where vector addition and scalar multiplication are defined, following specific axioms.

Question: What is the result of lim⁡x→0sin⁡(x)/x\lim_{x \to 0} \sin(x)/xlimx→0​sin(x)/x?

Answer: The limit lim⁡x→0sin⁡(x)/x\lim_{x \to 0} \sin(x)/xlimx→0​sin(x)/x equals 1.

Question: What is a symmetric matrix?

Answer: A symmetric matrix is a square matrix that is equal to its transpose.

Question: Define the term ‘Probability’.

Answer: Probability is a measure of the likelihood that an event will occur, ranging between 0 and 1.

Question: State the Pythagorean theorem.

Answer: The Pythagorean theorem states that in a right triangle, a2+b2=c2a^2 + b^2 = c^2a2+b2=c2, where $c$ is the hypotenuse.

Question: What is the Laplace transform of eate^{at}eat?

Answer: The Laplace transform of eate^{at}eat is 1s−a\frac{1}{s – a}s−a1​.

Question: Define a ‘Prime Number’.

Answer: A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself.

Question: What is the Taylor series expansion of exe^xex?

Answer: The Taylor series expansion of exe^xex is 1+x+x2/2!+x3/3!+…1 + x + x^2/2! + x^3/3! + \ldots1+x+x2/2!+x3/3!+….

Question: What is the standard deviation?

Answer: The standard deviation measures the amount of variation or dispersion in a set of values.

Question: State the Mean Value Theorem.

Answer: The Mean Value Theorem states that for a continuous function $f$, there exists a $c$ in $(a,b)$ such that f′(c)=f(b)−f(a)b−af'(c) = \frac{f(b) – f(a)}{b – a}f′(c)=b−af(b)−f(a)​.

Question: What is the determinant of a 2×2 matrix [abcd]\begin{bmatrix} a & b \\ c & d \end{bmatrix}[ac​bd​]?

Answer: The determinant is $ad-bc$.

Question: What is the sum of an arithmetic progression?

Answer: The sum is Sn=n2(a+l)S_n = \frac{n}{2} (a + l)Sn​=2n​(a+l), where $a$ is the first term, $l$ is the last term, and $n$ is the number of terms.

Question: What does it mean for a function to be continuous?

Answer: A function is continuous if it is defined at a point, its limit exists at that point, and the function’s value equals its limit.

Question: What is the difference between a scalar and a vector?

Answer: A scalar is a quantity with only magnitude, while a vector has both magnitude and direction.

Question: What is the area of a circle?

Answer: The area of a circle is πr2\pi r^2πr2, where $r$ is the radius.
