Methods
𝑠𝑖𝑛𝑥 𝑑𝑥 = −𝑐𝑜𝑠𝑥 + 𝑐
𝑐𝑜𝑠𝑥 𝑑𝑥 = 𝑠𝑖𝑛𝑥 + 𝑐
sec 𝑥 𝑑𝑥 = ln | sec 𝑥 + tan 𝑥| + 𝑐
csc 𝑥 𝑑𝑥 = −ln | csc 𝑥 + cot 𝑥| + 𝑐
tan 𝑥 𝑑𝑥 = ln | sec 𝑥 | + 𝑐
cot 𝑥 𝑑𝑥 = −ln | csc 𝑥 | + 𝑐
Trig Integrals
See Population Problem, pg. 269.
 We now know how to solve this
QUICKLY!!!

Separation of Variables
Know how to substitute given values into
R(t) = 𝑎0 𝑒 𝑘𝑡 formula.
 Be able to recognize derivative (rate of
change, instantaneous rate, slope of
tangent, etc.) vs. integral (sum, area
under curve, total accumulation).
