I feel annoyed because I can't rearrange something like this... ^^;;e
Anyway, how do I rearrange this:
Can you please list the steps for me?
Thank you, that helps a lot.
But for the equation you arrived at, , why is the sign in the bracket an addition sign? Shouldn't it be a subtraction sign?
So, if I wanted to rearrange this: into the , what would I need to do?
Apparently, you just want to write 0.2178x- 2.731 as B(x- C). You can do that by "factoring out" 0.2178. 0.2178x- 2.731= 0.2178(x- 2.731/0.2718)= 0.2178(x- 10.04783) so "3.123 sin (0.2178x-2.731)+18.43= 3.123 sin(0.2178(x- 10.0483)+ 18.43.
That is "A sin B(x- C)+ D" with A= 3.123, B= 0.2178, C= 10.0483, and D= 18.43.
