Second Fundamental Theorem of Calculus

If f(x) = 2๐‘ฅcos ๐‘ก ๐‘‘๐‘ก, find fโ€™(x).

If g(x) = 15๐‘ฅ๐‘’2๐‘ก ๐‘‘๐‘ก , find gโ€™(x).

Separation of Variables

See Population Problem, pg. 269.

We now know how to solve this QUICKLY!!!

Exponential Applications

The function ๐‘“ ๐‘ฅ = 100๐‘’ .15๐‘ก gives the size of

a rabbit population after t years.

a) How many rabbits are there after 10 years?

b) When does the population reach 1000?

c) What is the instantaneous rate of change of the population after 10 years? What are the units?

Exponential Growth/Decay

Know how to substitute given values into R(t) = ๐‘Ž0๐‘’

๐‘˜๐‘ก formula.

Be able to recognize derivative (rate of change, instantaneous rate, slope of tangent, etc.) vs. integral (sum, area under curve, total accumulation).
