Thank you. Although, I hoped that I shouldn't rely on analysis, since I would like to use sage to calculate the answer to compare with my own calculations and analysis. With MATLAB for instance, the answer can be given without doing any analysis. Is this possible with sage? 2017-02-18 21:21:18 +0200 received badge ● Nice Question (source) 2017-02-18 20:13:43 +0200 asked a question How to find inverse laplace transform Hi! I'm trying to find the inverse laplace transform from the following equation: (5 * s * e^(-2*s))/(s^2 + 9).inverse_laplace(s,t), although sage responds with: ilt((5 * s * e^(-2*s))/(s^2 + 9)). How do I find the inverse laplace transform from the equation above?

My question is how to formulate a command in sage so that the result will be of the same form as that in my checklist. It's not a question of getting a correct answer, but of how the output is displayed. 2015-10-14 15:20:20 +0200 commented question eigenvectors of complex matrix It is the vector that corresponds to a given eigenvalue. It represents the vector by which translation to the same vectorspace can be done by a translation matrix or a eigenvalue. Eigenvectors can generate a basis for the vectorspace, with no higher dimension than the original vectorspace. I'm sorry if the explanation is not all correct, I'm used to discuss linear algebra in danish. Anyways, how does your question answer mine? 2015-10-14 09:11:57 +0200 received badge ● Editor (source) 2015-10-14 09:11:18 +0200 asked a question eigenvectors of complex matrix Hi! I would like to find the complex eigenvectors of this matrix: A=matrix(CDF,[[2-i,0,i],[0,1+i,0],[i,0,2-i]]).  I have used the command A.eigenvectors_right() and I get the following eigenvectors (rounded off): (-0.70711+9.4136e-17i , 0 , 0.70711), (0,1,0), (0.70711 , 0 , 0.70711)  In my checklist I should get the vectors: t1(-1,0,1), t2(0,1,0), t3*(1,0,1), where the t-values are complex factors. How do I compute this kind of result?

Sincerly Simon 2015-08-17 19:38:14 +0200 asked a question how to get simplified result of solving equation Hi there! In a linear algebra assignment I have the following equation I need to find a solution for: -2*sqrt(3)*sin(t)^2+2*cos(t)*sin(t)+sqrt(3)==0. I know the result is pi/3. Now, when I use solve, solve(-2*sqrt(3)*sin(t)^2+2*cos(t)*sin(t)+sqrt(3)==0, t). I get: [sin(t) == -1/6*sqrt(3)*(sqrt(cos(t)^2+6)-cos(t), sin(t) == 1/6*sqrt(3)*sqrt(cos(t)^2+6)+cos(t))].  How do I use the solve function to get the more simplified result? NB: I have also tried to use find_root and different simplify functions, but also without any luck. I am new to sage, so it is quite possible that I don't know a specification to the solve function which I should use. Thank you in advance! Sincerly Simon
