1. II 1dxdy
A={(x,y),(x^2+y^2)^2=5(x^3+y^3),y>=0}

2. III xzdxdydz
A={(x,y,z),0<=z<=sqrt(x+y),y^2<=x, x<=1}

3. II xy/(x^2+y^2) dS
B={(x,y,z); z=1+xy, x^2+y^2<=2y, x>=0}

4. eliminacni metodou urcete :
x'+7x-9y=0
y'+x+y=3cos(t)

Je-li x(0)=0, y(0)=0

5. Nejaka teorie o potencialu a o soustavach DR.
