I think those people had nothing better to do, that's why they came out with so many rules and identities.
And now, because of these people I have to learn the stupid/ idiotic Trigonometry.
I've been trying to figure out how to prove and solve all those questions for the whole afternoon.
But till now I still have no idea.
In my secondary school days, I thought that TOA CAH SOH was already bad enough.
Now I'm in poly, I still have to know about :
basic identities,
Pythagorean identities,
double angle identities,
triple angle identities,
sum and difference identities,
product identities
and
sum and difference of two angles.
It's like so WTH can.
I will fail my quiz tomorrow, all thanks to those ancient Egyptians and Babylonians.
Shit them la.
