Question

what is ln of -e^-2.40/theta

Answer 1

ln e^-x = 1/x

Answer 2

there is a negative in front of e

Answer 3

i don't think you can ln a negative

Answer 4

i'm guessing that negative doesn't matter in my case

Answer 5

i was hoping it would matter :)

Answer 6

ln (-(1 / e^2.4) / theta), yea doesnt matter

Answer 7

Log [-e^(-2.4)/θ]
Log [-1/E^(2.4)*θ]]
= Log[-0.09071795328941251/θ]

Answer 8

but you can't log a negative

Answer 9

-e^x/theta
integrate from 2.40 to 0 and set it equal to .520
solve for theta

Answer 10

-e^2.40/theta - [-e^-0/theta] = .520
-e^-2.40/theta + 1 = .520
e^2.40/theta = .48
-2.40/theta = ln(.48)
theta = 3.2699

i was trying to ln the limit 0 at first and that's why i was having problem.
yay for perseverance :)
