I have to find a system of linear equations to determine a quadratic polynomial
p(x) = ax2+bx+c
Given the conditions:
p(1) = f(1)
p'(1) = f'(1)
p''(1) = f''(1)
where f(x) = xex-1
I know:
p(x) = ax2+bx+c
p'(x) = 2ax +b
p''(x) = 2x
f(x) = xex-1
f'(x) = ex-1 +...
I have to produce the reduced row echelon form of the following matrix:
A = | cos(x) sin(x) |
| -sin(x) cos(x) |
I am just learning Linear Algebra, and I am in the early Chapters of my book, so I can only use the Gauss method or the Gauss-Jordan method for...
