I am autistic and have difficulty understanding certain things for (sometimes) no apparent reason. This is one of those times. I am in need of help, and would appreciate some explanation. Thankyou! Please simplify it as much as possible.

Imagine you have a line-segment that is one length long.
One end is fixed to a horizontal line AND the angle between the horizontal and the segment, we’ll call Alpha.
Sin(Alpha) x (Length of Segment) = the height of a second line-segment that is attached to the original line segment and which drops down (vertically) to the horizontal line.
Cos(Alpha) is similar but is the distance along the horizontal line from the point where the original line-segment connects, to the point where the Sin vertical line-segment meets the horizontal line.
When original line-segment length changes, the Sin(Alpha) & Cos(Alpha) need to be products (i.e. multiplied) to get the height or length of the Sin Cos functions.
