b) Q2
c) Q
a)
d) Q​

Answer 1

Answer:

gruen equation sim sinxtcorx =n can be best solued by nit and trial method i.e if we take x=0 then

n=sin0(sin0+cos0)=0

that in maverce a solution Again if ule. Fake x=45 then

n=sin45∘(sin45∘+cos45∘)=12–√(12–√+12–√)=12–√×22–√=22=1

thin is alro a Momible value of n But after this there is no Moscole integal value values n has 2 integral valus
