Trigonometry and calculus were always two of my favourite maths topics. Matrix manipulation and statistics not so much. I think I just focussed on what I needed for an engineering career. But these days, as long as I can calculate how many beans make five (a bean and a half, a bean and a half, a half a bean and a bean and a half), I'm happy enough.
Don't shoot me, I'm only the piano player. I DON'T work for or on behalf of EON.Next, but am willing to try and help if I can. Not on mains gas, mobile network or mains drainage. House heated almost entirely by baby dragons.
