3. Key in R and press f , key in T and press f , then key in P and press
f Continue at step 5.
4. Key in X and press f , key in Y and press f , and key in Z and press
f .
5. To key in a second vector, press W E (for enter), then go to step 2.
6. Perform desired vector operation:
a. Add vectors by pressing W A;
b. Subtract vector one from vector two by pressing W S;
c. Compute the cross product by pressing W C;
d. Compute the dot product by pressing W D and the angle between
vectors by pressing f .
7. Optional: to review v
1
in polar form, press W P, then press f
repeatedly to see the individual elements.
8. Optional: to review v
1
in rectangular form, press W R, then press f
repeatedly to see the individual elements.
9. If you added, subtracted, or computed the cross product, v
1
has been
replaced by the result, v
2
is not altered. To continue calculations based on
the result, remember to press W E before keying in a new vector.
10. Go to step 2 to continue vector calculations.
Variables Used:
X, Y, Z The rectangular components of v
1
.
U, V, W The rectangular components of v
2
.
R, T, P The radius, the angle in the x–y plane ( θ), and the angle
from the Z axis of v
1
(U).
D The dot product
G The angle between vector ( γ )
Example 1
A microwave antenna is to be pointed at a transmitter which is 15.7
kilometers North, 7.3 kilometers East and 0.76 kilometers below. Use the
