I know that we all aren't in the sixth grade, so here's an easy way to use sin and cos

First, I have created an ability called "Sin and Cos". Let's open it!

Inside is a repeat forever block. Inside of that is a set position block. For "X" pick sin. Pick the first bubble and make it 125

Now for the bubble that reads sin. Go to values, and make a new value for your object called "turn":

For the last part insert "text X position"

Great! Now time for Y!

Instead of sin, pick cos. (cosine)

The first bubble will read 100.

Cos will be the value "turn" like sin. Finally, finish it with the last bubble reading "text Y position":

Great! Make sure that's in a Reapeat forever block!

Now, exit out and start a new rule. Pick when _ = _:

Now write when 7=7, then continue.

For this we'll need a value. So, go to the YELLOW "Values" tab and pick "increase value". In the value box, (first one) pick turn. For the number pick 5:

Great! Now hit play and watch!
