Get started for freeShow that each of the following matrices is orthogonal and find the rotation and/or reflection it produces as an operator acting on vectors. If a rotation, find the axis and angle; if a reflection, find the reflecting plane and the rotation, if any, about the normal to that plane.
Verify the calculations in (6.15) ,(6.16), and (6.17) .
Let . (a) Find a unit vector in the same direction as A . Hint: Divide A by . (b) Find a vector in the same direction as A but of magnitude 12 . (c) Find a vector perpendicular to A . Hint: There are many such vectors; you are to find one of them. (d) Find a unit vector perpendicular to A . See hint in (a).
Find the equation of the plane through and perpendicular to both planes in Problem 22.
For each of the following problems write and row reduce the augmented matrix to find out whether the given set of equations has exactly one solution, no solutions, or an infinite set of solutions. Check your results by computer. Warning hint:Be sure your equations are written in standard form. Comment: Remember that the point of doing these problems is not just to get an answer (which your computer will give you), but to become familiar with the terminology, ideas, and notation we are using.
