sunku :)

2sin(π/4)-1=0

sin(π/4)=0.5 WTF?

as nesuprantu tai ta visa padalinti π/4 ir kas tada gaunas?

sin(π/4)=sin(180/4)=sin(45)=0.707106781

0.707106781 nelygu 0.5

as tai su arcsin daryciau :)

oj turejo but sin(p/4x:)

[tex]sin(\pi/4x)=0.5[/tex]
[tex]\pi/4x = (-1)^k*\arcsin{0.5}+\pi*k[/tex]
[tex]\pi/4x = (-1)^k*\pi/6+\pi*k[/tex]
dalinam is pi viska ir dauginam is 4

[tex]1/x = (-1)^k*4/6+4*k[/tex]
[tex]x = \frac{1}{(-1)^k*4/6+4*k}[/tex]
[tex]x = \frac{1}{(-1)^k*2/3+4k}[/tex]

gal galite padeti? 3x+12y+2z+7=0 kaip issireikst X=....; y=....; z=....;?
