COMEDK UGET 2026 Calculus Practice Questions with Solutions
Score high marks with COMEDK UGET 2026 Calculus practice questions with solutions. COMEDK Calculus sample questions are prepared after analyzing the past few years' question paper trends, and cover important topics, like Limits and Derivatives.
Preparing COMEDK UGET 2026 Calculus Practice Questions with Solutions is a decisive step if you want to secure a strong score in Mathematics, as Calculus consistently contributes a significant number of questions inCOMEDK UGET 2026 exam. As you work through practice questions with solutions, you gradually build conceptual clarity, speed, and confidence—three essentials for this time-bound exam. The most important portions from Calculus that you must focus on include Limits & Continuity, Differentiability, Applications of Derivatives (AOD), Indefinite and Definite Integrals, Area Under Curves, and Differential Equations. These topics not only carry high weightage but also allow for repeated practice with standard methods, making them scoring if prepared systematically.
When you analyze the type and nature of questions asked, you will notice that COMEDK favors concept-based, application-oriented MCQs rather than lengthy calculations. Questions from Limits and Continuity often test standard limits, graphical understanding, and continuity at a point. Differentiability questions usually involve checking differentiability using left-hand and right-hand derivatives or applying basic derivative rules. From Applications of Derivatives, expect questions on monotonicity, maxima–minima, tangents and normals, and increasing–decreasing functions. In Integral Calculus, previous years have frequently asked standard integrals, properties of definite integrals, and direct formula-based questions on Area Under Curves, while Differential Equations questions are generally straightforward, focusing on formation and solution of first-order differential equations.
To prepare this chapter effectively, you should start by strengthening your NCERT fundamentals, as most questions are directly or indirectly based on standard results and methods. Practice a wide variety of previous year–level questions topic-wise, and always analyze solutions to understand shortcuts and common traps. While solving practice sets, aim for accuracy first, then speed, especially in Differentiation and Integration. Maintaining a small formula notebook for limits, derivatives, standard integrals, and properties of definite integrals will help in quick revision. Finally, you should regularly attempt mixed Calculus practice tests so that you learn to switch between subtopics smoothly—this approach ensures you are fully prepared for any Calculus question that appears in COMEDK UGET 2026.

COMEDK UGET 2026 Calculus Practice Questions with Solutions
COMEDK Calculus practice questions will help you gain a better understanding of concepts and fundamentals. In the following section, we have listed down some of the most important COMEDK UGET 2026 Calculus practice questions with solutions:
Q1. Which of the following function is injective?
a. f(x) = |x +2|, x ∊ [ –2, ∞)
b. f(x) = x2+ 2, x ∊ (- ∞, ∞)
c. f(x) = 4x2+ 3x - 5, x ∊ (- ∞, ∞)
d. f(x) = (x - 4) (x - 5), x ∊ (- ∞, ∞)
Ans.a. f(x) = |x +2|, x ∊ [ –2, ∞)
Solution:Let's examine each option to check for injectivity. A function is injective (one-to-one) if different inputs always produce different outputs. In other words, for any two numbers a and b in the domain, if f(a) = f(b) then a = b.
Below is a breakdown of each option:
Option a: f(x) = |x +2|, x ∊ [ –2, ∞)
For x ≥ -2, the expression x + 2 is non-negative, so the absolute value function simplifies:
f(x) |x + 2| = x + 2
The function now is a linear function, f(x) = x + 2, which is strictly increasing over the domain [-2, ∞)
Because an increasing linear function never repeats the same output for different inputs, this function is injective. Thus option a is correct.
Q2.
a. -3/2
b. 1/2a3/2
c. 1/2
d. 2a-3/2
Ans.b. 1/2a3/2
Solution:The given limit is in the form of 0/0 as x →0. . To solve this, we will use the rationalization method.
Multiplying both numerator and denominator by the conjugate of the numerator, we get:
Now, we can directly substitute x = 0 into the expression, to get:
1/√[a(a+0)(√a+0 + √a)]
Simplifying the equation,
1/2a3/2
Q3. If Sin y = x(cos(a+y)), then find dy/dx when x = 0:
a. 1
b. Sec a
c. Cos a
d. -1
Ans.c. Cos a
Solutions:If Sin y = x(cos(a+y)), then find dy/dx when x = 0
Differentiating both sides of the equation with respect to x, we get
Cos ydy/dx = cos (a+y) + x(-sin(a+y)dy/dx
Cos y dy/dx + x sin (a+y)dy/dx = cos(a+y)
dy/dx(cos y + x sin(a+y)) = cos(a+y)
dy/dx = cos(a+y)/[cos y+xsin(a+y)]
When x = 0, we have
dy/dx = cos(a+y)/cos y
Since Sin y = xcos (a+y), when x = 0, we have sin y = 0. This implies y = 0 (since we are looking for the derivative at x =0)
Therefore, x = 0.
dy/dx = cos(a+0)/cos0 = Cos a.
Q4. The rate of change of the volume of a sphere with respect to its surface area S is?
a. 1/2√S/π
b. √S/π
c. 2/3√S/π
d. 1/4√S/π
Ans.d. 1/4√S/π
Solution:To find the rate of change of the volume of a sphere with respect to its surface area, we first need to express both the volume and the surface area in terms of the radius of the sphere.
The volume V of a sphere is given by the formula:
V = 4/3 πr3
The surface area S of a sphere is given by the formula:
S = 4πr2
We need to find the rate of change of V with respect to S, which is expressed as dV/dS. To do this, we use the chain rule:
dV/dS = dV/dr.dr/dS
First, we find dV/dr,
dV/dr = d/dr(4/3πr3) = 4πr2
Next, we find dS/dr,
dS/dr = d/dr(4πr2) = 8πr
Now, we need to find dr/dS. Since dS/dr = 8πr
we can write: dr/dS = 1/8πr
Finally, we substitute, dV/dr and dr/dS back into the chain rule expression:
dV/dS = (4πr2).(1/8πr) = r/2
We know from the surface area formula that S = 4πr2. Solving for r in terms of S, we get:
r2= S/4π = √S/4π
Substituting this back into dV/dS, we get:
dV/dS = 2/s√S/4π = 1/2.1/2√S/π = 1/4√S/π
Q5. The area enclosed by the pair of lines x = 0, the line x - 4 = 0 and y + 5 = 0 is
a. 10 square unit
b. 20 square unit
c. 50 square unit
d. 5/4 square unit
Ans.b. 20 square unit
Solution:We have,
xy = 0, x - 4 = 0, y + 5 = 0
x = 0, y = 0, x = 4, y = -5
So, area enclosed = Area of rectangle of OABC
AB X BC
5 X 4 = 20 square unit.
