Parametric to Cartesian Conversion:
From: | To: |
Parametric to Cartesian conversion is the process of eliminating the parameter (typically t) from parametric equations to find a direct relationship between x, y, and z coordinates. This converts equations from parametric form (x(t), y(t), z(t)) to Cartesian form (F(x,y,z) = 0).
The calculator takes parametric equations in terms of t and attempts to eliminate the parameter:
Process: The calculator solves one equation for t, then substitutes into the others to eliminate the parameter.
Details: Cartesian form is often more intuitive for visualization and analysis, making it easier to identify geometric properties like symmetry, intercepts, and special points.
Tips: Enter expressions for x(t), y(t), and z(t) using standard mathematical notation. The parameter must be 't'. For example:
Q1: What types of parametric equations can be converted?
A: The calculator works best with polynomial, rational, and simple trigonometric parametric equations.
Q2: What if the parameter can't be eliminated?
A: Some parametric forms (particularly those with transcendental functions) may not have a closed-form Cartesian representation.
Q3: How accurate is the conversion?
A: The calculator provides exact symbolic conversion when possible, but some approximations may be needed for complex equations.
Q4: Can this handle 2D parametric equations?
A: Yes, simply leave z(t) as 0 or a constant for 2D conversions.
Q5: What notation should I use for exponents and functions?
A: Use ^ for exponents (t^2), * for multiplication, and standard function names (sin, cos, exp, etc.).
