Change in what? Change in time.
Change in z, or maybe y.

All I’m asking, is for a little Respect,
When you take derivatives
dz
When you take derivatives
When you take them,
When you take derivatives
dt
When you take derivatives

dy’s just a little change in height,
dx is a run, but o so slight,
ratios of differentials happen with respect
they’re just a little bit, just a little bit.

IM-P-L-I-C-I-T find out what it means to me,
IM-P-L-I-C-I-T take with respect to t.
