1           Integrate(1-11), derive(12-17) or solve the exponential funtions!
2                   What did the math book say to the other?                                     Answer key
3   1) (0)∫(1) e^(-2x) dx                                                       Don’t: 1.965
4   2) (3)∫(4) e^(3-x) dx                                                       hey: .935

6   4) (-2)∫(0) (x^2)e^(.5(x^3)) dx                                             said: 5.789
7   5) (1)∫(3) e^(3/x)/(x^2) dx                                                 forever: .5e^(x) - .5e^(-x)
8   6) (0)∫(2^.5) xe^(-.5(x^2)) dx                                              date: y = e^x

10   8) (1.047)∫(1.571) e^(sec2x) sec2xtan2x dx                                  lie: dy/dx = 2e^(x)cosx
11   9)dy/dx = xe^(a(x^2))                                                       done: dy/dx = (2e^2x)/(1 + e^2x)
12   10)dy/dx =((e^x)-(e^-x))((e^x)-(e^-x))                                      problems: dy/dx = .5(x^-.5)(e^(x^.5))
13   11)dy/dx = sinx + e^(2x)                                                    dog: y = -sinx + e^(2x) + .5x - 1.25
14   12)y = e^(x^.5)                                                             own: y = e^(2x) + e^(-2x) - 2x + c
15   13)y = ln(1 + e^2x)                                                         my: y = .5ae^(a(x^2)) +c
16   14)y = (e^x)(sinx + cosx)                                                   talking: .116
17   15)y = e^(1-x) Point (1,1)                                                  got: -.198
18   16)y = (x^2)(e^x) - (2x)(e^x) + 2e^x Point (1,e)                            mind: .632
19   17)y = .5(e^x) + .5(e^-x)                                                   remember: .654
20   18)3^2x = 75                                                                I've: .316
21   19)5^6x = 8320                                                              cook: .632
22   20)2^(3-x) = 625                                                            me: .432
