this is my question: A Building sways 55cm to the right from origin in 5 seconds and 55 cm to the left of the origin in 35 seconds. And i am supposed to write an eqaution to define this. I'm guessing the is no amplitude no vertical translation and since it's sine basically im gonna need some help... Does anyone have any resources of GOOOD LIABLE EASY TO FOLLOW MATH SKILLS? My book Nelson Mathematics 11 with the rollercoaster in the front has a bunch of errors and misconceptions.
