"Cooking oil" is actually a broad term for purified fat derived from plants which is normally liquid at room temperature. "Vegetable oil," when used to label a cooking oil product may refer to a specific oil like rapeseed oil or to a blend of different oils. Not all vegetable oils are edible - some are useful only as fuel oils. Not all cooking oils are vegetable oils - for example there are several nut oils and oils from gourds and melons that can be used in cooking. The non-vegetable cooking oils are seldom used in baking, so for the purposes of baking, the terms cooking oil and vegetable oil are pretty much interchangeable.
