Final answer:
The correct option for a parametric equations of tangent line calculator in 3D is A. 3D Tangent Line Solver.
Step-by-step explanation:
The correct option for a parametric equations of tangent line calculator in 3D is A. 3D Tangent Line Solver. This calculator is specifically designed to calculate the equations of tangent lines in 3D space.
To calculate the tangent line in 3D, you need to know the parametric equations of the curve and the point on the curve where the tangent line is desired. The 3D Tangent Line Solver will use this information to determine the equation of the tangent line.
