Question

I have f(x)=sin(x+90) and I am so confused on how to graph this on my graph.

I understand that it is shifted << 90 degrees, but I am having a very hard time understanding how to graph when my graph does not extend past -365. I could graph f(x)=sin(x-90), by just shifting the starting point over 90, to -270. I guess I am having a hard time conceptually understanding. Is there any easy way to graph it?

Answer 1

use geogebra and plug that in, f(x)=sin(x+90)

Answer 2

you there? @AT123

Answer 3

like you said, shift to left 90 degrees
