Top 10 Most Repeated Maths Topics for JEE Mains 2026: If you are preparing for JEE Mains 2026, then just hard work is not enough; you also need some smart work, and one of the easiest ways is to find the topics that are asked frequently in the exam. JEE mains exam has three main subjects, out of which Maths is an important subject that follows a pattern where some chapters carry high weightage and are repeatedly asked. By focusing on these high-scoring and repeated topics, students can strengthen their preparation. In this article, we have provided the Top 10 most repeated topics for JEE Mains Maths 2026. If you want to appear for JEE advanced then it is very important to qualify this exam. JEE Main 2026 registration is now open, and candidates can submit their applications between 31 October 2025 and 27 November 2025. The Session 1 examination is scheduled from 21 to 30 January 2026.
The NTA published the JEE Mains admit card 2026 for session 1 exams in the afternoon. It has hosted two official links on the portal, jeemain.nta.nic.in. However, both the JEE admit card links were not working for some time, likely due to heavy traffic on NTA website. Currently, the first link uploaded by the NTA is active. Candidates can view and download their hall tickets using their registration number, password, and captcha code.

The topics asked in the JEE Mains exam follow a pattern where some chapters are asked more frequently than others. Focusing on these topics is important to strengthen your exam preparation and helps in maximising scores. Given below some most important and repeated topics that students should prioritise for JEE Mains 2026.
From the above table, it is clear that Linear Differential equation is the most important and repeated topic with 102 questions, the second is Area bounded by two curves with 79 questions. The huge gap between the first and second topics shows why we should give priority to the linear equation. Additionally, some topics like the Sum of n terms of an AP and the Quadratic Equation are often asked repeatedly.
Let’s go through the questions from each of the top 10 most repeated topics in Maths for JEE mains:
1. Linear Differential Equation
Question: If the solution curve of the differential equation $\left(\left(\tan ^{-1} y\right)-x\right) d y=\left(1+y^2\right) d x$ passes through the point $(1,0)$, then the abscissa of the point on the curve whose ordinate is $\tan (1)$, is
Question: Consider a curve $\mathrm{y}=\mathrm{y}(\mathrm{x}) {\text {}}$ in the first quadrant as shown in the figure. Let the area $\mathrm{A}_1$ is twice the area $\mathrm{A}_2$. Then the normal to the curve perpendicular to the line $2 \mathrm{x}-12 \mathrm{y}=15$ does NOT pass through the point.
$
2 \ln |f(x)|=\ln |x|+C
$
Simplify the logarithmic terms:
$
\ln |f(x)|=\frac{1}{2} \ln |x|+\frac{C}{2}
$
Exponentiate both sides:
$
|f(x)|=e^{\frac{C}{2}} \sqrt{x}
$
Let $e^{\frac{C}{2}}=k$, where $k$ is an arbitrary constant:
$
f(x)=k \sqrt{x}, \quad k \in \mathbb{R} .
$
and satisfy the $(10,-4).$
Hence, the correct answer is the option (3).
3. Dispersion (Variance and Standard Deviation)
Question: The outcome of each of 30 items was observed; 10 items gave an outcome $\frac{1}{2}-d$ each, 10 items gave outcome $\frac{1}{2}$ each and remaining 10 items gave outcome $\frac{1}{2}+d$ each. If the variance of this outcome data is $\frac{4}{3}$ then $|d|$ equals:
Question: A possible value of $x^{\prime}$, for which the ninth term in the expansion of $\left\{3^{\log _3 \sqrt{25^{x-1}+7}}+3^{\left(-\frac{1}{8}\right) \log _3\left(5^{x-1}+1\right)}\right\}^{10}$ in the increasing powers of $3^{\left(-\frac{1}{8}\right)} \log _3\left(5^{x-1}+1\right)$ is equal to 180, is :
Question: If the system of linear equations
$2 x-3 y=\gamma+5$ and $\alpha \mathrm{x}+5 \mathrm{y}=\beta+1$, where $\alpha, \beta, \gamma \in \mathbf{R}$ has infinitely many solutions, then the value of $|9 \alpha+3 \beta+5 \gamma|$ is equal to_________.
(1) 58
(2) 72
(3) 86
(4) 67
Answer:
$2 x-3 y=\gamma+5$
$\alpha \mathrm{x}+5 \mathrm{y}=\beta+1$
For infinite solutions, these two lines should coincide
Question: Let $\vec{a}=\hat{i}+\hat{j}+\hat{k}, \vec{b}$ and $\vec{c}=\hat{j}-\hat{k}$ be three vectors such that $\vec{a} \times \vec{b}=\vec{c}$ and $\vec{a} \cdot \vec{b}=1$ If the length of the projection vector of the vector $\vec{b}$ on the vector $\overrightarrow{\mathrm{a}} \times \overrightarrow{\mathrm{c}}$ is $l$, then the value of $3 l^2$ is equal to_________.
(1) 2
(2) 4
(3) 6
(4) 8
Answer:
Projection of $\vec{b}$ on $(\vec{a} \times \vec{c})=\frac{|\vec{b}(\vec{a} \times \vec{c})|}{\mid \vec{a} \times \vec{d}}=l$ .......(i)
Also $\vec{a} \times \vec{c}=\left|\begin{array}{rrr}i & j & k \\ 1 & 1 & 1 \\ 0 & 1 & -1\end{array}\right|$
$=i(-1-1)-j(-1)+k(1)$
$=-2 i+j+k$
$|\vec{a} \times \vec{c}|=\sqrt{4+1+1}=\sqrt{6}$
From (i)
$l=\frac{2}{\sqrt{6}}$
$\Rightarrow 3 l^2=3 \cdot \frac{4}{6}$
=2
Hence, the answer is the option (1).
7. Maxima and Minima of a Function
Question: Let the maximum area of the triangle that can be inscribed in the ellipse $\frac{\mathrm{x}^2}{\mathrm{a}^2}+\frac{\mathrm{y}^2}{4}=1, \mathrm{a}>2$, having one of its vertices at one end of the major axis of the ellipse and one of its sides parallel to the $y$-axis, be $6 \sqrt{3}$. Then the eccentricity of the ellipse is:
(1) $\frac{\sqrt{3}}{2}$
(2) $\frac{1}{2}$
(3) $\frac{1}{\sqrt{2}}$
(4) $\frac{\sqrt{3}}{4}$
Answer:
Area of $\underset{(A)}{\triangle \mathrm{ABC}}=\frac{1}{2} \times 4 \sin \theta \times \mathrm{a}(1-\cos \theta)$
