Hi all,
How do you go about solving this question as it says:
Show that the matrix:
| costheta sintheta 0 |
B= | -sintheta costheta 0 |
| 0 0 1 |
is invertible for all values of theta [Hint. Show that det(B) is not...
Hi Don,
If I'm correct, the parametric equation for the following points is:
x = -2t + 5, y = -9t - 6 and z = -2t + 10
So no values are matching this parametric
x = 2 + t; y = 3 - 3t, z = 4 + 2t.
So therefore it does not lie on the line right?
Hi all,
How do I go about solving the following question?
Determine whether the points (5 , -6 , 10) and (3, 3 , 8) are on the line
x = 2 + t; y = 3 - 3t, z = 4 + 2t

Hi all,
How do you go about solving the following Question?
Find an equation of the plane containing the point (1 , 1 , -1) and perpendicular to the line through the points (2 , 0 , 1) and (1 , -1 , 0).

Hi all,
How do u go about doing this question?
x - 2y +z =4
y- z =3
(a^2 - a - 2)z = a+1
Determine values of a for which the system has no solution, one solution and many solutions

Hi all,
How do you find out if this Parametric equation
x = -2t + 3 ; y = -t - 1 ; z = -3t + 2
Is perpendicular to this parametric equation
x = -2 + 6t ; y = 3 - 6t ; z = -3 - 2t
Thanks

Hi all,
What is the formula of an equation of a plane that is parallel to the plane.
For example the plane is x - 3y -2z -4 = 0 going through a point(1 , 1, 1).
Thanks,
Stephen
Hi all,
I got this question from a past exam paper does the point (8 , 4 , -5) lie on the plane 7x - 3y + 4z = 8?
Do you work it out as follows because can't find this example in my Linear Algeria book?
7(8) - 3(4) + 4(-5) = 8
56 - 12 - 20 = 8
24 is not equal to 8
Therefore the...
