sin L= pierw 3/3
cosL = pierw 6/3
A* tg L = cos L
A* sinL / cos L = cos L /* cos L
A * sin L = (cos L)*(cos L) /:(sinL)
A = [ (cos L)*(cos L)] :(sin L)
A = [(pierw 6/3)*(pierw 6/3)]:(pierw 3/3)
A = 2/3*pierw 3
A = 2(pierw 3)/3
Zad. 2)
a1=?
q = ?
a1 + a3 = 5
a3 - a1 = 3
2*(a3) = 8 / :2
a3 = 4
a1 = 1
a1*q^2 = 4
1*q^2 = 4
q = 2 lub q = - 2
a1 = 1 lub q = - 2
a7 = a1*q^6
a7 = 1*2^6
a7 = 64
Odp: Siódmy wyraz ciągu geometrycznego wynoi 64.
