Book Question: Why is y=f(x) not continuous at a?
Book Answer: f(a) is not defused.

What does "defused" mean?

Thank you
 


I do not think that this is common mathematical terminology.

Perhaps, it's a typographical error. The statement makes sense if we replace the word defused with the word defined.

What type of book is this, and when and where was it published?

C'mon - Defused means Defined .... ? !
 
It is a Schaum's Outlines "Mathematics fo Physics Students".
The copyright is 2007 but it was probably written decades ago.
Your answer leads me to believe I will not miss anything by skipping the book's answer to this particular problem.
Thank you for your assistance - much appreciated.
 
I reckon f(a) is a bomb that has not been defused :roll:


Are you doubly sure it actually says 'defused'?. This is in an old Schaum's outline book?.

I have one that is Schaum's Advanced Math for Engineers and Scientists. It does not have 'defused' in it as part of the continuity definition.

I agree with Aladdin. I am sure it should really read 'defined'.

I have Schaum's Calculus Fifth edition It does not have 'defused' in it as part of the continuity definition ...
 
And I doubt if you find it anywhere else. No offense to the OP, but I think that is a mistake. Either that, or a big typo in the book.

Ah ha! To me, this explains all.

I once read a Schaum's Outline. (I think it was an algebra review.)

It was so riddled with errors (many glaring), that I mailed the book's ashes to the publisher, along with a note explaining how Schaum's benefits compost more than students.
