The gallbladder is a small pouch that sits just under the liver. The gallbladder stores bile produced by the liver. After meals, the gallbladder is empty and flat, like a deflated balloon.efore a meal, the gallbladder may be full of bile and about the size of a small pear. In response to signals, the gallbladder squeezes stored bile into the small intestine through a series of tubes called ducts. Bile helps digest fats, but the gallbladder itself is not essential.
U-substitution is for functions that can be written as the product of another function and its derivative. $$\int u du$$. Integration by parts is for functions that can be written as the product of another function and a third function's derivative.
Subsection LT Linear Transformations. Definition LT Linear Transformation. A linear transformation, T:UâV, is a function that carries elements of the vector space U (called the domain) to the vector space V (called the codomain), and which has two additional properties. T(u1+u2)=T(u1)+T(u2) for all u1,u2âU. T(Î±u)=Î±T(u) for all uâU and all Î±âC.
