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has been
replaced by the result, v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
