is there a website or a program that can perform inverse or transpose of a matrix that has variables...?

T = [(cosd(X))^2 (sind(X))^2 2*sind(X)*cosd(X);
(sind(X))^2 (cosd(X))^2 -2*sind(X)*cosd(X);
-sind(X)*cosd(X) sind(X)*cosd(X) (cosd(X))^2 - (sind(X))^2];

I have this matrix, and im trying to find the inverse or transpose in terms of variables.. so i can multiple this matrix by another matrix.

[Q_bar] = [T^-1] *[Q] * [T]

where Q matrix are numbers...

transpose is just flipping columns and rows. you can quickly do that by hand or use excel's transpose.

yea u right , forget transpose.

how about inverse?

it's just 3x3. you can probably find a formula for each element. shouldn't take more than a few min to solve it.
from a quick google search

its gonna be very tedious... with the sins and cos..

wolframalpha?

Throw it into matlab. Easiest way

Tried.




What's the command for inverting a symbolic matrix

did you even TRY googling? it's the first hit.

inv(A)
