(Note: writing AA -1 means A times A -1) 2x2 Matrix OK, how do we calculate the inverse? Well, for a 2x2 matrix the inverse is: a b c d −1 = 1 ad−bc d −b −c a b = -1/2 + √ 5/4 Since a square root has two values, one positive and the other negative b 2 + b - 1 = 0 has two solutions: b = -1/2 + √ 5/4 or b = -1/2 - √ 5/4 Note that √ 5/4 can be written as √ 5 / √ 4 which is √ 5 / 2 . Thus, this comes down to finding a collection of invertible matrices which commute. Why is b= (a+=1) an invalid syntax in python? Python a, b = b, a +b. Guides.. First, subtract #color(red)(1/b)# from each side of the equation to isolate the #a# term while keeping the equation balanced: #1/a + 1/b - color(red)(1/b) = 1/f - color(red)(1/b)# #1/a + 0 = 1/f - 1/b# #1/a = 1/f - 1/b#. So: ( B − 1 A − 1) ( A B) = B − 1 ( A − 1 A) B = B − 1 I B = ( B − 1 I) B = B − 1 B = I. A − 1 is known and I want to calculate ( A + B) − 1. To write −1 b - 1 b as a fraction with a common denominator, multiply by a a a a. One way to do this would be to note that det(AB)= det(A)det(B).3. Q1.
