24if I remember correctly..this was the only good question in NCERT max/min chap..[3]
find all tangents to the curve y=cos(x+y), -2∩≤x≤2∩ that are parallel to the line x+2y=0

241on solving u get reach to the conclusion that x+y =n∩+∩/2...now how to proceed
24okk i ma writing a btit of soln
dy/dx=-sin(x+y) . [1+ dy/dx]
put dy/dx=-1/2
=>sin(x+y)=1
=>cos(x+y)=0
=> y=cos(x+y)=0
=>sin(x+0)=1 =>x=pi/2 ,-3pi/2 (u know why ..)
=>pts are (-3pi/2 ,0) ad (pi/2 ,0)
now finsih it up
1ufff... how stupid of me..... i was lookin at sin(x+y)=1 for hrs and couldnt figure it out.... thanx mentor
1but are'nt u edudigm mentor..... if not then how did u answer as a mentor...?
24am I????
i dont think I am...
maybe i have to ask nishant sir abt this..
