Dude trying to get it from first principles!
Which is what I also lean towards. Give it to me step by step and I need to clearly map out each one... then the mind wanders and when I snap back to attention, I've lost the plot already, my mathematical surroundings are unclear, disorienting.
Add to this an erratic series of math teachers - some of them good, some of them blah - and this day trigonometry to me is a jumbled mess, but I loved calculus and was pretty good at probability and statistics.
