The following equation is the expression of the left hand side as a sum of partial fractions with rational numbers as coefficients. On the right hand side, A and B are constants and the numerator of the third term is missing

x^3−14x^2+26x−11/ = A/ . . . +B/ . . . . . . C/
. . (x−2)^2(x^2+3). . . .(x−2) . (x−2)^2 . (x^2)+3.

1.Supply the numerator of the last term giving appropriate names to the coefficients.
2.Determine the coefficient B.
3.Determine the remaining coefficients, including those in the missing numerator.

Define what is meant by saying that a column vector v is an eigenvector for the square matrix A and that (h) is the corresponding eigenvalue. Verify that v = [2, 5]T is an eigenvector for the matrix

A = −38 ...14
......−105 .39

and determine the corresponding eigenvalue.

1) Use calculus to determine an approximate value for 2 / cube root of 7.8, leaving your answer correct to 4 decimal places.

2) Differentiate sqrt (x^2 + 9) with respect to x and hence find the exact value of the intergration of (3x) / sqrt (2x^2 + 18) with limits 0 to 4.

*Please show all essential workings. Thanks (:
