Hello, I am a bit confused as how line integrals can exist in 2D. For 2D, we are dealing with two variables: x and y. For 3D, we are dealing with three variables: x,y and z=f(x,y), such that f(x,y) = x+y. Since line integrals use the x and y components as inputs and f(x,y) = z as the output, should not line integrals exist in 3D always?

Fundamental Theorem of Line Integrals Consider the line integral: ∮_C▒〈6xy+6x, 3x^2-3 cos⁡(y) 〉 ∙dr ⃗ where C is the line segment from the origin to (4, 5). Evaluate this integral by rewriting the integral as a standard single variable integral of the parameter t. Without finding a potential function show that the integrand is a gradient field. Find a potential function for the vector field. Use the Fundamental Theorem of Line Integrals to evaluate this integral.
