Sorry, the thread title is meant to be "Cant type this in my calculator correctly!".
Hi all,
I cant seem to get the correct answer to this equation (attached image):
The answer is -0.06 as shown in the question, but when I complete it in my calculator I get a different answer
Staring at this question for hours now.
(What I do: I first complete the the 2nd bracket and then multiply that by 108/365 which gives me 0.02739. I then hit the Ln button on my calculator and do 2510/2600 and add that answer to my 0.02739. Next I type 0.2306 SQUAREROOT(108/365) which gives me -0.01847)
Any pointers would be really apprecaited.
Thanks everyone.
Thank you Sudharaka,
I dont think the problem is the calculator but rather me entering in the expression incorrectly.
I have tried it again and again and still keep getting it wrong (I am not much of a mathematicial you see), would you by any chance be able to give me a little more of a break down on how to enter the expressions correctly in my calculator?
I dont see where I am going wrong, maybe I am using the Ln feature incorrectly (again, I am not much of a mathematician im afraid)
Thank you again.
If in doubt use google: Google Calculator
Without knowing what model of calculator you have (or how it treats logs) we cannot answer comprehensively.
