Hello sir I require the IIT JEE Important Maths Formula so can you please provide me it ??

As you are demanding for the IIT JEE Important Maths Formula provided below:

IIT JEE Important Maths Formula

1. General form of Complex numbers x + iy where x is Real part and
y is Imaginary part.
2. Sum of nth root of unity is zero
3.If the two roots are negative, then a, b, c will have same sign
4. If the two roots are positive, then the sign of a, c will have different
sign of 'b'

5.Three roots of a cubical equation are A.P, they are taken as a – d, a,
a + d

Matrices

1. Asquare matrix in which every element is equal to '0', except those
of principal diagonal of matrix is called as diagonal matrix
2. A square matrix is said to be a scalar matrix if all the elements in
the principal diagonal are equal and Other elements are zero's
3. Adiagonal matrix Ain which all the elements in the principal diagonal
are 1 and the rest '0' is called unit matrix
4. A square matrix A is said to be Idem-potent matrix if A2 = A,
5. A square matrix A is said to be Involu-ntary matrix if A2 = I
6. A square matrix A is said to be Symm-etric matrix if A = AT
A square matrix A is said to be Skew symmetric matrix if A=-AT
7. A square matrix A is said to be Nilpotent matrix If their exists a
positive integer n such that An = 0 'n' is the index of Nilpotent
matrix
