Hey all,
If a question asks to find a maximum on a complex curve and there is only one turning point, are we still expected to find the double differential?
For example, in the 2005 Maths paper, question 10 (b) (iv)
http://www.boardofstudies.nsw.edu.au/hsc_exams/hsc2005exams/pdf_doc/maths_05.pdf
There is only one turning point here. Do we still have to double differentiate to prove that it is a maximum?
All insight is much appreciated![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
Thanks!
