A problem on parametric vector form of the plane

In summary, the conversation discusses finding a vector equation for a plane with given parametric equations and moves the question to a different homework section. The provided vector equation is \vec{r}(t_1,t_2)= x(t_1, t_2)\vec{i}+ y(t_1, t_2)\vec{j}+ z(t_1, t_2)\vec{k} with specific vectors and constants.

hi...

please help me this question.
i am not understand this question.

Find a vector equation of the plane for the following parametric equations:
X= 1 +2t1 – 3t2
y = 3 + 4t1 – 4t2
z = 2 + 3t1 – 5t2

i just want a solution, just let me know if possible.

A "vector equation" for any surface, with parameters [itex]t_1[/itex] and [itex]t_2[/itex] is
[tex]\vec{r}(t_1,t_2)= x(t_1, t_2)\vec{i}+ y(t_1, t_2)\vec{j}+ z(t_1, t_2)\vec{k}[/tex]


1) This looks like a homework problem.

2) Though it talks about "vector", this is not really a "Linear and Abstract Algebra" question.

I am moving it to the "Calculus and Beyond" homework section.

Welcome to PF, Syeda_Nadia! :smile:

I believe your vector equation would be:
[tex]\begin{pmatrix}x\\y\\z\end{pmatrix} = \begin{pmatrix}1\\3\\2\end{pmatrix} + t_1 \begin{pmatrix}2\\4\\3\end{pmatrix} + t_2\begin{pmatrix}-3\\-4\\-5\end{pmatrix}[/tex]
 

FAQ: A problem on parametric vector form of the plane

What is the parametric vector form of a plane?

The parametric vector form of a plane is a way to express the equation of a plane using two vectors and a point on the plane. It is written as r = p + sa + tb, where r is a position vector, p is a point on the plane, and a and b are two direction vectors.

How is the parametric vector form of a plane different from the standard form?

The parametric vector form is different from the standard form because it uses vectors and a point to describe the plane, while the standard form uses the coefficients of x, y, and z to represent the plane's equation. Additionally, the parametric vector form allows for more flexibility in terms of direction and position on the plane.

How do you convert from the standard form to the parametric vector form of a plane?

To convert from the standard form to the parametric vector form, you can use the following steps:

  1. Identify the coefficients of x, y, and z in the standard form equation: ax + by + cz + d = 0
  2. Choose a point on the plane and use it as the point p in the parametric vector form.
  3. For the direction vectors a and b, set each coefficient of x, y, and z in the standard form equal to the corresponding coefficient in the parametric vector form, and solve for a and b.

What is the significance of the direction vectors in the parametric vector form of a plane?

The direction vectors a and b in the parametric vector form of a plane represent the two independent directions on the plane. The vector a determines the direction of the plane in the x-y plane, while the vector b determines the direction of the plane in the y-z plane. Together, these vectors define the orientation of the plane in 3-dimensional space.

How is the parametric vector form of a plane used in real-world applications?

The parametric vector form of a plane is commonly used in fields such as physics, engineering, and computer graphics. It can be used to represent the position and orientation of objects in 3-dimensional space, as well as to calculate intersections and distances between planes. It is also used in vector calculus to solve problems involving surfaces and volumes in 3-dimensional space.
