Running in circles

[barush]

I've been just listening to The Scientist by Coldplay and it's literally made me cry. I'm probably turning into a sap as songs never make me cry. Well not anymore it seems. Oh well.

Other than that, I've realized I totally don't get maths. At all. Usually I understand at least smt to get at least 3 from a test (1 is the best, 5 the worst, for the ones who dunno), but not this time around. Nada. Equation of a circle, who the Hell needs that anyway? God, I hate maths.

I'll probably give up on it and try to write. I've been stupid enough to promise another fic so I'd better make it at least readable.

Er, slov tady fuckt moc neni:D Ale je to hlavne equation of a circle a pak circle and a straight line a mutual position of a circle and a line. Ovsem vzhledem k tomu ze pisem zitra, tak uz se te base nevyhnu.. lol

mno tak budto primka muze kruznici protinat nebo ji neprotina.

jednoducha kruznice je treba x*x+y*y=4 (stred v (0,0) a polomer 2)

primka o rovnici y=0 (to je osa cela osa x) ji protina, coz zjistis tak, ze dosadis co znas do rovnice kruznice: x*x+0*0=4 vidis, ze rovnice je pekna a da se vyresit: x=-2 a x=+2, coz jsou x-ove souradnice pruseciku. y-ove souradnice zjistis tak, ze dosadis do rovnice kruznice:
2*2+y*y=4 --> y=0
(-2)*(-2)+y*y=4 --> y=0
pruseciky jsou tedy (-2,0) a (2,0)

primka o rovnici y=4 (rovnobezka s osou x prochazejici bodem (0,4) ) kruznici neprotina. stejnym postupem si dosadis do rovnice kruznice:
x*x+4*4=4 a zjistis, ze je rovnice hnusna a nevyslo by ti x realne, pac x*x=-12
takze se neprotinaj

nevim, co vic se da k tomuto tematu rict :))

The Scientist is one of the songs I listen to when I'm feeling down. It helps. =)

Also, maths is evil. Quick! Kill it with fire!
