Ever have undergone the “excruciating” years in

 

            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.
