For each of the following pairs of functions ff and gg, determine if the level curves of the functions cross at right angles, and find their gradients at the indicated point. a) f(x, y)=5x+5y,

g(x, y)=5x−5y.

Do the level curves of f and g cross at right angles? gradfientf(6,5) = ? gradient(6,5) = ?

b) f(x, y)=x^2−y,

g(x, y)=2y+ln(|x|)

Do the level curves of f and g cross at right angles? gradfientf(6,5) = ? gradient(6,5) = ?

one that is bigger than 3 1/2

answer: the answer is simply nothing.

step-by-step explanation: because there is no ending to this question

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
