Find the general solution of x'=(-cos t, sin t). ( this is 2×1 matrix with -cos t on top, sin t on bottom.) Please use the method of undetermined coefficients. 9/29/2013 | Sun from Los Angeles, CA | 1 Answer | 0 Votes Mark favorite Subscribe Comment Comments Sun, you are missing the 2x2 matrix that makes this a differential equation. 9/29/2013 | Andre W. But I already got that part. 9/29/2013 | Sun from Los Angeles, CA Comment
Question is not clear. It should be determinant: l Cost - sint l = cos^{2 }- (-sint) (sint) = cos^{2 }+ sin^{2 }t =1 l cost sint l 9/30/2013 | Parviz F. Comment
