Question

hey.Help me here please. sin (x-pi/4)-1=0

Answer 1

\(\large \sin (x-\frac{\pi}{4})-1=0\)

u wanna find x right ?

Answer 2

let \(x-\frac{\pi}{4}=y\)
\(\large \sin (y)-1=0\)
\(\large \sin (y)=1\)

Answer 3

now wich \(y\) value gives u
\(\large \sin (y)=1\)
\(\large y=\frac{n \pi}{2}\)
right ?
cuz
\(\large \sin (\frac {\pi}{2})=1\)

Answer 4

got it untill nw ?

Answer 5

thanks

Answer 6

ur wlc ,
but still u need to find x :)

Answer 7

ok

Answer 8

:)
ok

Answer 9
