Line Integral Calculator

Compute the line integral of a vector field F along a given parametric curve r(t).

Line Integral Formula:

For vector field F and curve r(t):

∫_C F · dr = ∫_a^b F(r(t)) · r'(t) dt

Where:
- F = 
- r(t) = 
- r'(t) = derivative of r(t) with respect to t

Enter all functions in standard math notation. For 2D, leave F_z and r_z empty.
