T:R ->R3 T(x, y, z) = (2x + 5y − 3z, 4x + y − 5z, x − 2y − z)
(a) Find the matrix representing this transformation with respect
to the standard basis. (b) Find the kernel of T, and a basis for
it. (c) Find the range of T, and a basis for it.
Consider the system of equations
2x-5y=a
3x+4y=b
2x- 4y=c
where a, b, c are constants. Because there are 3 equations and 3
unknowns, there are no possible values of a, b and c for which the
system of equations has a unique solution. True or false?
Find the roots of the following equation in [−π, π] 2x 2 − 4
cos(5x) − 4x sin x + 1 = 0 by using the Newton’s method with
accuracy 10^(−5) .
how do I solve this using a computer
f(x,y)=sin(2x)sin(y)
intervals for x and y:
-π/2 ≤ x ≤ π/2 and -π ≤ y ≤ π
find extrema and saddle points
In the solution, I mainly interested how to
findcritical points in case of the system of trigonometric
equations (fx=0 and fy=0).
