Napisać równanie płaszczyzn dwusiecznych kątów między płaszczyznami: 2x-y+5z+3=0 i x-5y+2z-1=0
2x - y + 5z + 3 = 0 i x - 5y + 2 z - 1 = 0
1)
2x - y + 5z + 3 + 1*(x - 5y + 2z - 1) = 0
czyli
3x - 6y + 7z + 2 = 0
===================
2)
2x - y + 5z + 3 - 1 *( x - 5y +2z - 1) = 0
x + 4y + 3 z + 4 = 0
=====================
