i wonder why..

garrrghhh why is it that i cant visualize 3D trigo?!

even after the full employment of my rulers, pencils, calculators, hands, toes, everything in a futile attempt to illustrate a 3D version of whats printed in the math paper... i still cant see angle BOP.

GRR. this is so frustrating. i can visualize everything. EXCEPT 3D trigo.

weekends arent very productive. my brain's self-declared break. shut-down point.

all i've learnt today.. is that tweety bird is actually a guy.
