matt grime Posted May 15, 2005 Share Posted May 15, 2005 If I were to ask ou to solve the equation assuming a,b,c,and d are non-zero real numbers of: a(x+1/b)+d=c You could do it without thinking. This question is no harder (though we just must remember that AB doesn't equal BA for all matrices). Link to comment Share on other sites More sharing options...

matt grime Posted May 15, 2005 Share Posted May 15, 2005 You need to have more confidence in yourself. This, after all, is maths, and it is more important you understand how you got the answer than what the actual (numerical) answer is. Link to comment Share on other sites More sharing options...
