Q.  
To determine the coefficients of the equation two end points and the two tangent vectors. This statement is true for which of the following


Discuss

Answer :   Option:- B

Explanation :

The statement about determining coefficients from endpoints and tangent vectors refers to the Hermite Cubic Spline Curve. This type of curve is defined by two endpoints and two tangent vectors, allowing for smooth transitions between the points. Hermite splines are widely used in computer graphics, animation, and other fields where smooth curve fitting is required. They provide control over both the position and the slope at each endpoint, giving designers flexibility in shaping curves.
