| Vol 2, Three
Skills for Algebra covers many topics in algebra and
logic that students starting calculus should have mastered or will
have to master. Also includes arithmetic review problems to catch
common mistakes. A fourth skill gives a unifying theme
for high school maths. |

Partial Elimination of Units
Suppose y = f(x) as above. For the first case, let x = X ·u2. Then
y = h(X) where h(X) = f(X·u2). In the equation
y = h(X) units have been eliminated from the discussion
of one quantity, but not the other. (A situation close to this occurs
in the common treatment of simple interest and
compound interest computations. See below.)
Now slopes of the graph of y versus X has units
|
|
units of y
units of X |
= |
units of y
1 |
= units of y |
|
For a second case of partial elimination, let y = Y·u1. Then
So the graph of Y versus x has units
|
|
units of Y
units of x |
= |
1
units of x |
|
|
Thus the units of a slope depend on which units are retained
or eliminated. Examples follow.
