Hi,

Please answer and explain. I am pretty confused.

Thanks

# 4 ) Let s be a quadratic surfacegiven by 4 x 2 + yz + 2 2 2 = 10(a) classify J:. S is a hyper boloid of two sheets. S is an elliptic paraboloid. S is an ellipsoid. S is a hyper boloid of one sheet. S is an elliptic cone( b ) Find a unit normal N to s at ( 1, 2, 1 )N ="( ) Find the equation of the tangentplane to s at the point( 1 , 2 , 1 ) :Answer :
