Ever since before I entered junior high, given

that many have said I am blessed because of having skills in

Mathematics-related kind of stuff, I became totally curious once I had heard

numerous different math terms and topics I had never heard and encountered

before in my grade school years from different people like my siblings – since they

are older than I. These terms include trigonometry, circular functions, algebra,

matrix, vector, polynomial functions, conjugate, rationalize, integration and

many more.

In

my junior high years, I admit that some of these terms and topics were

challenging for me, and had that difficulty that made me read all the lectures

that had discussed again and again until I became satisfied with my

understanding on that certain topic.

That adventure, honestly, was so fun. With that in mind, I truly hoped

that my journey would have had the same fun as before. That’s when before I

entered senior high school.

Calculus,

such a simple word to hear yet a complex and a rational word indeed, they say.

My brothers had told me, even though this one is difficult, but if it is me, I

can just remove the dirt on my shoulders, figuratively. Knowing how hard that

topic is after hearing such reviews and feedbacks from different persons who

have undergone the “excruciating” years in studying calculus, I now bother

researching and finding helpful videos to make me have background knowledge on the

said subject.

One of the leading branches of

mathematics is calculus. It is a study of

continuous change, in the same mathematical sense in algebra’s and geometry’s;

the study of shapes, and the study of generalizations respectively. It has two

major fields: one is differential

calculus – it deals

with the rates of change and slopes of curves. It also studies the

behavior and rate on how different quantities change. And the second one is called integral calculus that has to deal with the accumulation of

quantities and the areas between and under curves as well. Even though the said

fields are said to be polar to each other since integration is the opposite of

differentiation, they are still linked and are related to each other by

the fundamental

theorem of calculus. Both fields make

use of the fundamental notions of convergence of infinite sequences and infinite series to a well-defined limit.
