Hmmmm.... works for me.    Watch ABOVE the calculator to see if it is interpreting your input the way you intended....

Im doing a tafel plot to get trying to get a unitless coeffecinet, It work if i solve the Ln itratively then subtract but not with the quotient rule :( but this leaves me with a unit to coeffecient which should be unit less 

 

ln2.66= 0.98

ln-0.79=-0.2303 

 

-0.2303+0.98=0.7497 number i want 

but 

...........................................

and then it clicks, i should be using the product rule not Quoteint as im adding not subtraction, why math should not be done a 1:22am :/
