=> x+y = npi/2 where n is an odd integer

So basically these are set of parallel lines each with slope -1 with intercepts as nÎ /2

btw i think u had asked this once dont remember

(2n+1)pi/2 not npi/2 I think

sin2θ=sin2α
=>θ=nπ±α

So (x+y)=nπ ± π2

Are u guys missing this ?? or have u included those cases too ??

same thing na ?

npi ± pi/2 is the same as npi/2 where n is odd isnt it?

i am a bit surprised that none of you are thinking that this is same as

cos (x+y) = 0

:D
