What do you mean by adjoint of matrix?

0 0 3

Sagar Khandelwal replied | 19/11/2016

In linear algebra, the adjugate, classical adjoint, or adjunct of a square matrix is the transpose of its co factor matrix. The adjugate has sometimes been called the "adjoint", but today the "adjoint" of a matrix normally refers to its corresponding adjoint operator, which is its conjugate transpose.

Find the equation of the circle having (1, -2) as its centre and passing through 3x + y = 14, 2x + 5y = 18?

Hussam Uddin replied | 22/11/2016

Equation of circle is (x-1)2 + (y +2)2 = r2 , we need to find r , point of intersection of 2 lines is 13x = 52, x= 4 , y = 2, therefore r2 = 25.
