Answer:
A) Non-collinear- does not lies on straight line
B) Collinear- lie on straight line
Step-by-step explanation:
We have to check collinearity of three points.
The points are said to be collinear if,
A) A(2, 5, 3), B(3, 7, 1), C(1, 4, 4)
Thus, the given points are not collinear.
B) D(0,-5,5), E(1,-2,4), F(3,4,2)
Thus, the given points are collinear.
Answer:
Step-by-step explanation:
Given
(0, 1, 0)
The vector equation is given as:
Substitute values for x, y and z
Differentiate:
The parametric value that corresponds to (0, 1, 0) is:
Substitute 0 for t in r'(t)
The tangent line passes through (0, 1, 0) and the tangent line is parallel to r'(0)
It should be noted that:
The equation of a line through position vector a and parallel to vector v is given as:
Such that:
and
The equation becomes:
By comparison:
and
The parametric equations for the tangent line are:
