ఒక చరరాశి t కి సంబంధించి f(x) ప్రమేయం విలువ యొక్క మార్పు రేటు దీని ద్వారా ఇవ్వబడుతుంది: \(\rm \frac {df(x)}{dt}\)
గణన:
ఇవ్వబడిన ఘనం యొక్క భుజం L = 10సెం.మీ మరియు \(\rm dL\over dt\) = 4 సెం.మీ/సె
ఇప్పుడు ఘనం యొక్క ఘనపరిమాణం V = L3
\(\rm dV\over dt\) = \(\rm dV\over dL\) × \(\rm dL\over dt\)
\(\rm dV\over dt\) = \(\rm dL^3\over dL\) × 4
\(\rm dV\over dt\) = 3L2 × 4
\(\rm dV\over dt\) = 12 × 102
\(\rm dV\over dt\) = 1200 సెం.మీ3/సె
