11after getting f(x)=secx for maxima minima points
substitute it in the question and integrate i am getting another f(x) there
maybe we can check that function for maxima and minima again[7]
1hey i think itz -cosx or secx im i rite.........i thinked in another manner
1GUYZ DA FINAL ANSWER FOR MAX. IS 1-e and for min 1 - e^-1
does anyone of u get it using y=sec(x)???????????????
1i think some thing much more be mention for finite value but if not mentioned then i got min. as -∞ & max. as +∞ i m write plz reply
1YEAH!!!!!!!!1
GOT IT!!!!!
JUS USE DA ABOVE FORMULA TO DIFFERENTIATE!!!!
THEN U GET A DIFF EQN.
WHICH ON SOLVIN GIVES Y = 1-e^sinx
therefore min max r 1-e^-1 and 1-e.....
CREDIT GOES 2 CELESTINE!!!!!!!!!
THNX A TON CELE!!!!!
11Does this have something to do with the Newton-Leibnitz theorem?
1heyyy...... not this way..
this is a differential eqn... in linear form..
dy/dx - ycosx = -1
p(x) = -cosx
find integrating factor : e∫pdx n then do all those traditional works....
1But how will you integrate???
u'll get f(x) = ∫f(x)cosx - x + c
wat alll operations can u do on this f(x) to get da maxima??
This que was a more than one correct ans type que. and both the max. min. wer part of the rite answers!!!!!!
1yes i think i got it...
f'(x) = f(x)cosx - 1 .
now integrate.
we will find f(x) .
then we can do all operations on f(x).
1the for min value is 1-e
and for max value is 1 - (1/e)
secx = f(x) at max/min does not solve the prob ne.....
21try this out by differentiatin n then making a differential equation.
looks a tough nut to crack...
1CMON PPL.....
AB TO ANS KI HINT BHI DE DI......
PLZZZ.... GIVE ME SUM IMPORTANT BREAKTHROUGH
1MAK!!!!
U cant apply uv rule n solve coz still f(x) or f'(x) (whichever u take as v) remains which is not integreable!!!!!
the ans is in terms of e....
plzzz tell notify me if ne1 gets it
13i didn't solve it clearly... let aatmanvora try it again... if he doesn't get, then lets solve it...
if v solve it completely n provide it to him... that would be as worst as spoon-feeding... [6] [4]
