solve for x, in the form x = loga/logb for 2^(4x - 1) = 3^(5-2x) (taken from OCR June 2014 C2)

We can take logs of both sides straight away, and using the log rule that alogb = log(b^a)So(4x-1) log(2) = (5 - 2x) log(3)We can expand the bracketsso (4x)log(2) - log(2) = 5log(3) - 2xlog(3)We can group th...

Find the eigenvalues and eigenvectors of A = ([2, 0 , 0], [0, 1, 1], [0, 3, 3])

We can use the characteristic equation, det(A - k I) = 0 to find the eigenvalues of A. Performing this, we see that(2-k) * ( (1-k) (3-k) - 3 ) = 0.Immediately, we can see a root is k = 2, which is our first ...
