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?

I have looked online and everything is more advanced than this. Please help me!

Answer 1

instead of 90, you can see it as pi/2
the standard form of sinx is
