How does the life cycle of a star relate to the mass of the elements that it produces?
Initially, a star is mostly made up of hydrogen which keeps on fusing and producing a lot of energy in the form of heat and light.
Every star undergoes nuclear fusion, a process in which four hydrogen atoms join to form one helium atom; when enough hydrogen atoms have been converted to helium, more helium atoms fuse together to form new elements.
When iron is produced in the core of a star, the star starts to die. In a star, all elements are produced in this manner.

As stars evolve, they produce elements up to iron through fusion reactions; elements heavier than iron are produced during supernova explosions or other stellar processes. A star's life cycle determines the mass of the elements it produces through nuclear fusion processes. Stars with higher mass have higher core temperatures, allowing them to fuse heavier elements in their cores.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
