The Tangent Line of a Second Degree Polynomial calculator computes the tangent line for a second degree polynomial (y = a•x²+b•x +c).

INSTRUCTIONS:  Enter the following:

• a - the multiplicative constant for the term
• b - the multiplicative constant for the x term
• c - constant term

Tangent Line: The calculator returns the equation of the tangent line.

#### The Math / Science

The tangent line of a second degree polynomial is the first derivative.  Where:

y = a X² + b X + c

and the derivative of the second degree polynomial is:

y' = 2aX + b
