I want to make a to and fro motion on x using a sinusoidal equation. I saw it on a tutorial recently but i can't find it again.

Add a location keyframe for your object anywhere by hitting I in object mode and choosing Location.
In the Graph Editor select the keyframe for the X value, then go to the properties panel (hit N if you don't see it).
In the Modifiers tab choose Add Modifier > Built-In Function

Click the object's X Location to edit it, and type in #sin(frame/20).
This will create a driver with a scripted expression sin(frame/20) which sets the X location to the SIN of the current frame value divided by 20. Making the cube move on X between -1 and 1 every ~63 frames.
