Consider f and c below. f(x, y) = (7 + 8xy2)i + 8x2yj, c is the arc of the hyperbola y = 1/x from (1, 1) to 3, 1 3 (a) find a fu

KonstantinChe [14]

$\dfrac{\partial f}{\partial x}=7+8xy^2$

$\dfrac{\partial f}{\partial y}=8x^2y$

The first equation gives

$f(x,y)=7x+4x^2y^2+g(y)$

Differentiating with respect to $y$ gives

$8x^2=8x^2y+\dfrac{\mathrm dg}{\mathrm dy}\implies\dfrac{\mathrm dg}{\mathrm dy}=0\implies g(y)=K$

for some constant $K$ . So

$f(x,y)=7x+4x^2y^2+K$

and by the fundamental theorem of calculus,

$\displaystyle\int_C\nabla f\cdot\mathrm d\vec r=f\left(3,\frac13\right)-f(1,1)=25-11=\boxed{14}$

Step-by-step explanation:

A. Prove that angles 1 and 3 are vertical.

1. $\angle 1, \angle 2$ - linear pair of angles

2. $m\angle 1+m\angle 2 =180^{\circ}$ - linear pair of angles are supplementary

3. $\angle 2, \angle 3$ - linear pair of angles

4. $m\angle 2+m\angle 3 =180^{\circ}$ - linear pair of angles are supplementary

5. $m\angle 1+m\angle 3 =m\angle 2+m\angle 3$ - substitution property of equality

6. $m\angle 1 =m\angle 3$ - subtraction property of equality

7. $\angle 1\cong \angle 3$ - definition of congruent angles.

So, any two vertical angles are congruent.

B. Prove that angle 3 and angle 5 are congruent.

1. $\angle 1\cong \angle 5$ - Corresponding Angles Postulate

2. $m\angle 1=m\angle 5$ - definition of congruent angles

3. $\angle 1\cong \angle 3$ - vertical angles

4. $m\angle 1=m\angle 3$ - definition of congruent angles

5. $m\angle 3=m\angle 5$ - substitution property of equality

6. $\angle 3\cong \angle 5$ - definition of congruent angles

So, alternate interior angles are congruent

C. Prove that angle 1 and angle 7 are congruent.

1. $\angle 1\cong \angle 5$ - Corresponding Angles Postulate

2. $m\angle 1=m\angle 5$ - definition of congruent angles

3. $\angle 5\cong \angle 7$ - vertical angles

4. $m\angle 5=m\angle 7$ - definition of congruent angles

5. $m\angle 1=m\angle 7$ - substitution property of equality

6. $\angle 1\cong \angle 7$ - definition of congruent angles

So, alternate exterior angles are congruent
