a) =sin(do drugiej)a + cos(do drugiej)a +2cos a*sin a - 2cos a*sin a=1
b) =tga + 1/tga - (tg(do drugiej)a - 2*tga *1/tga + 1/tg(do drugiej)a)=
=tga - tg(do drugiej)a +1/tga - 1/tg(do drugiej)a + 2
zad 2
1 + ctga = 1 + cosa/sina
b/a = (b/c)/(a/c)
b/a = b/a
ok
cos^2a+2cosasina+sin^2a-2sinacosa=cos^2a+sin^2a=1
zad2
1+ctga=sina+ctga
1=sina
