Zadanie2) Podaj kąty w stopniach: -1/6 л, 3л, 3/4 л
-1/6 л=x
π=180°
x=-1/6*180°π/π
x=-30°
3л=3*180°
3л=540°
3/4 л=x
π=180°
x=3/4*180°π/π
x=135°
Zadanie3) Oblicz: [tg π/6 *ctg π/3 +sin π/4]/ cos π/6=
Oblicz: [ √3/3*√3/3 +√2/2]/ √3/2 = [ 3/9 +√2/2]/ √3/2 =[ 1/3 +√2/2]*2/ √3=
2/3 √3 +√2/ √3 =2√3/9 +√6/3
Zadanie4) Oblicz: ( 6 po2) +(6 po3)=
6!/2!*4!+6!/3!*3!=6*5/2+6*5*4/2*3=15+5*4=35
a)
b) n!(n+1)!/(n-1)!(n+2)!=n*(n-1)!(n+1)!/(n-1)!(n+2)*(n+1)!=n/(n+2)
Zadanie5) Zastosuj dwumian Newtona dla : (2x – 1) ⁵
(2x – 1) ⁵ =1*(2x)⁵-5*(2x)⁴*1+10*(2x)³*1²-10*(2x)²*1³+5*2x*1⁴-1⁵
=32x⁵-5*16x⁴+10*8x³-10*4x²+10x-1=32x⁵-80x⁴+80x³-40x²+10x-1=
