Masteriza [31]

Answer:

perpendicular slope= 1/4

Step-by-step explanation:

F(x, y, z) = yzexzi + exzj + xyexzk,c: r(t) = (t2 + 4)i + (t2 − 1)j + (t2 − 2t)k, 0 ≤ t ≤ 2(a) find a function f such that f = ∇
exis [7]
\nabla f(x,y,z)=\mathbf f(x,y,z)=yze^{xz}\,\mathbf i+e^{xz}\,\mathbf j+xye^{xz}\,\mathbf k

\dfrac{\partial f(x,y,z)}{\partial x}=yze^{xz}
\implies f(x,y,z)=\displaystyle\int yze^{xz}\,\mathrm dx=\dfrac{yz}ze^{xz}+g(y,z)
f(x,y,z)=ye^{xz}+g(y,z)

\dfrac{\partial f(x,y,z)}{\partial y}=e^{xz}=e^{xz}\dfrac{\partial g(y,z)}{\partial y}
\implies\dfrac{\partial g(y,z)}{\partial y}=0\implies g(y,z)=h(z)
f(x,y,z)=ye^{xz}+h(z)

\dfrac{\partial f(x,y,z)}{\partial z}=xye^{xz}=xye^{xz}+\dfrac{\partial h(z)}{\partial z}
\implies\dfrac{\partial h(z)}{\partial z}=0\implies h(z)=C
f(x,y,z)=ye^{xz}+C
