Can someone please show me step by step how to normalize e^-5x in the interval (0, infinity)?
I have read a lot of different books etc but need it explained to me in plain English or showed to me step by step because I am just not getting it.
I assume you mean make the area under the curve 1.0 in the interval.
Area=Constant*INT e^-5x dx from 0 to infinity
1.0=constant* (-1/6 e^-6x ) over the limits
1.0= constant*1/6(e^0 -e^-inf)
check my work, My mind today is wavering, allergy meds today.
Thank you for responding so quickly. And sorry to hear about your allergies. They are not fun! The exact question was : normalize the following functions in the interval 0 to infinity: a) e^-5x. The answer my instructor has is 10^1/2 e ^-5x as the answer but I don't know how he got to that answer. Any ideas?
