Help me! I know how to draw graph like sin 2x , 2sin x , sinx +2, sinx -2 but my problem is how to draw for 1-sinx or 2-sinx ? I dont understand the principle behind this. Can anyone explain to me please? Thank You very much.
i know the standard graph of sinx, cosx and tanx. I also know that when there is like sinx +2, just shift the sinx graph up by two units. But i dont understand how to draw for 1-sinx or 2-sinx or questions like that. Do u understand me now? Please help me.
Hello, helloying!
It takes only a bit of algebra . . .
I know how to draw graph like: $\displaystyle \sin2x,\;2\sin x,\;\sin x +2,\;\sin x -2$
but my problem is how to draw for $\displaystyle 1-\sin x$ or $\displaystyle 2-\sin x$
If we have: .$\displaystyle y \:=\:2-\sin x$
. . factor out -1: .$\displaystyle y \:=\:-(\sin x - 2)$
You know the graph of: $\displaystyle y \:=\:\sin x - 2$
. . It is the sine curve, lowered two units.
Then: .$\displaystyle y \:=\:{\color{red}-}(\sin x - 2)$ is the same graph
. . reflected ("flipped") over the x-axis.
