Math 1304 Calculus I 3.8 – Exponential Growth
Applications: Things that grow proportional to their size • Physics • Some nuclear reactions (explosions) • Chemistry • Some chemical reactions (explosions) • Biology • Populations (people, animals, plants) • Individuals (size) • Geology • Some pressure, force, heat • Psychology • Mental growth, … • Economics • Some cost, production volume, profit, overhead • Compound interest
Differential Equation • For the equation: dy/dt = k y • Solution (Th 2 on page 234) The only solutions are y(t) = y(0) e kt
Exercises • See examples and problems in section 3.8.
