Hi Simna,

The JEE has two papers. Paper 1 consists of Physics, Chemistry and Mathematics. And paper 2 consist of Drawing, Aptitude Test and Mathematics. The syllabus is almost same for Mathematics in Paper1 and Paper 2. Only some topics differs. 

Syllabus for Mathematics of Paper 1-

Sets, Relations & Functions, Matrices & Determinants, Permutations & Combinations, Complex Numbers & Quadratic Equations, Binomial Theorem, Mathematical Induction, Limit, Sequences & Series, Differential Equations, Integral Calculus, Continuity & Differentiability, Three Dimensional Geometry, Co-ordinate Geometry, Statistics & Probability, Vector Algebra, Mathematical Reasoning and Trigonometry.

Syllabus for Mathematics of Paper 2-

Sets, Relations and Functions , Quadratic Equations, Matrices and Determinants, Complex Numbers, Mathematical Induction, Sequences and Series , Limits, Continuity and Differentiability,, Applications of Binomial Theorem, Permutations and Combinations, Integral Calculus, Differential Equation, Vector Algebra, Co-ordinate Geometry, Three Dimensional Geometry, Trigonometry, Probability, Statistics, and Mathematical Reasoning.

Hope this helps. All the best!!
