Matematika 3, Prucha, 21.01.99

1. II xy+2y+z dxdy
A={(x,y),x^2+y^2=<2x,y<=x}

2. III y+3 dxdydz
A={(x,y,z),0<=z<=x^2-y^2, x>=0, y>=0, x+y<=4}

3. II |xy| dS
B={(x,y,z); x+z<=2, x^2+y^2=4}

4. reste (neurceno jak) :
x' = y - 8*sin(t)
y' = -2x + 2y - 13*cos(t) - 10*sin(t)
takhle nejak vypadaly poc. podminky:
x(0)=1;
y(0)=2;


5. Stokesova veta + odhad lin. dif. rovnic;
