Indefinite Integration: Complete Notes for JEE Mains & Advanced

Indefinite Integration – Complete Revision (JEE Mains & Advanced) Indefinite Integration is not about memorising random formulas — it is about identifying forms . JEE strictly rotates questions around a fixed set of standard integrals and methods . This note covers the entire official syllabus with zero gaps. 1. Definition \[ \int f(x)\,dx = F(x)+C \quad \text{where } \frac{dF}{dx}=f(x) \] 2. ALL Standard Integrals (Must Memorise) \(\int x^n dx = \frac{x^{n+1}}{n+1}+C,\; n\neq-1\) \(\int \frac{1}{x}dx = \ln|x|+C\) \(\int e^x dx = e^x+C\) \(\int a^x dx = \frac{a^x}{\ln a}+C\) \(\int \sin x dx = -\cos x + C\) \(\int \cos x dx = \sin x + C\) \(\int \sec^2 x dx = \tan x + C\) \(\int \csc^2 x dx = -\cot x + C\) \(\int \sec x\tan x dx = \sec x + C\) \(\int \csc x\cot x dx = -\csc x + C\) 3. SIX IMPORTANT FORMS (JEE CORE) Form 1: \(\int \frac{1}{x^2+a^2}dx\) \[ = \frac{1}{a}\tan^{-1}\frac{x}{a}+C \] Form 2: \(\int \frac{1}{\sqrt{a^2-x^2}}dx\) \[...

JEE Mains 2026 Chemistry Revision: Mole Concept Notes, Formulas & PYQ Patterns

  StudyBeacon JEE Mains 2026 — Revision Capsule #1: Mole Concept 30-Second Refresher The mole connects particles ↔ mass ↔ volume ↔ concentration . Most Physical Chemistry problems reduce to converting between these. Essential Ideas (Ultra-Compressed) One mole = Avogadro number \(N_A = 6.022\times10^{23}\) particles. Moles ↔ mass: \(n=\dfrac{W}{M}\) (mass ÷ molar mass). Gases at STP: \(1\ \text{mol} = 22.4\ \text{L}\). Ideal gas: \(PV=nRT\). Watch units. Concentration: Molarity \(M=\dfrac{n}{V_{\text{soln}}}\), Molality \(m=\dfrac{n_{\text{solute}}}{\text{kg solvent}}\). Equivalents useful for redox/acid-base: \(n_{\text{eq}}=\dfrac{W}{\text{equivalent mass}}\). High-Yield Formulas (Memorize) n = W / M moles = mass ÷ molar mass n = V / 22.4 (gases at STP) PV = nRT idea...

50 Most Repeated Physics MCQs: Class 12 CBSE

  50 Most Repeated Physics MCQs: Class 12 CBSE Solved & Optimized for Board Exams 2026 All questions follow the latest CBSE MCQ pattern. Click the "Solution" dropdown to check your accuracy. Unit 1: Electrostatics & Current Electricity Q1. A dipole is placed in a uniform electric field. It experiences: (a) Force only (b) Torque only (c) Both force and torque (d) Neither force nor torque उत्तर (Solution) Ans: (b) Torque only. In a uniform field, net force is zero ($qE - qE$), but since the forces act at different points, they produce torque. Q2. If the distance between two charges is doubled, the electrostatic force becomes: (a) 1/2 times (b) 2 times (c) 1/4 times (d) 4 times उत्तर (Solution) Ans: (c) 1/4 times. $F \propto 1/r^2$. So, doubling $r$ makes $F$ one-fourth. Q3. Which of the following is the unit of Electric Flux...
