Calculus is the mathematical study of continuous change. it is in the same way that geometry is the study of shape and algebra is the study of operations and their application to solving equations (Mathematical Formulas for Industrial and Mechanical Engineering, 2014).

STEM students and aspiring STEM students, If you want to study in advance or have an idea on what topics will be discussed in the future, watch the video below. Until again, Deitures!

APP001: FORMULIA

Tharseo [Administrator] | 15 December 2021

My Deitures! Are you having a hard time in your calculus class? Don't worry, me too! That's why today, I'm going to share an application that helps me in my calculus class. And I hope that it will help you to! It's called Formulia by Mario Chavarria. This app is for Android users only.

EXPL001: LIMIT

Movere [Administrator] | 15 December 2021

Deitures! I discovered that for you to easily understand calculus, especially in the limits. Here's my tips for you to easily understand the limits

Let's say that f(x) = x²-4/x-2 , what is f(2)? Can we evaluate the function at x=2? If we plug in f(2)= 2²-4/2-2 = 0, therefore we can't evaluate the functions at x=2. This when limits become important. So if we can't find out the value of the function when x=2, can we find out what the function will do as x approaches 2. So what happens when x=2.1. f(2.1)= 2.1²-4/2.1-2 = 4.1, now what if we plug in a number that's even closer to 2 let's say 2.01. f(2.01)= 2.01²-4/2.01-2 = 4.01, do notice that as x gets closer and closer to two the value of the functions gets closer and closer to four. So thus we can use limit expressions. Lim x→2 = x²-4/x/2 We know that is equal to four but to show you work what you need to do is factor x²-4. Lim x→2 = (x+2)(x-2)/x-2. We could cancel the same factor x-2. So the only left is Lim x→2 = x+2, so now we can now evaluate the 2 to the x.

Lim x→2= (2)+2 = 4. This tells us that as x gets closer and closer to 2 the the Y value or f(x) will approach a value of 4.

Hello fellow Deitures! Did I do it right? It's actually my first time sharing here, so please treat me well. Anyway, I would like to share this video for students who are not that good at calculus. I hope this will help you, as it helped me. That's all, thank you.

EXP002: REFERENCE ANGLE

Epistêmê [Administrator] | 16 December 2021

How are you doing, Deitures? A few days ago a friend of mine gave me a tip in getting the reference angle of an angle. It's very helpful for me so I'm sharing it here for you, Deitures, to see.

In finding the reference angle, If the given was negative you will need to find the coterminal and for you to do that you need to add the given to 360 after getting the sum subtract it to 180 then you can now find your reference angle. for example: the given is -160 since it's negative add 360 and that will give you 200. Subtract 180 from 200 and that will be 20. So your reference angle is 20.
