Focus on the parts of the problem that you already understand, and work through as much of it as you can. In the process of rehashing familiar concepts, you may trick your brain into forming the complete solution.

Even more than mathematical ability, calculus requires creativity, adaptability, and excellent problem-solving skills. If you work hard, take care of yourself, and use our guide to enhance your calculus capabilities with these brain-boosting tips, there should be nothing stopping you from earning that A.

Differential calculus looks at the instantaneous rate of change. So, what does that mean? A function is typically notated like this: For an equation to be a function, any number you plug in as the x variable has to cause the equation to equal precisely one value of y.

An independent variable is a value of x in a function. A dependent variable is whatever value is yielded by the function, represented in our example as y. The value of y will change depending on the value of x , the independent variable. The value of the independent variable always determines the value of a dependent variable.

The domain of an equation or function is a set of all the possible values of the independent variable x that will produce a valid dependent variable y. While the domain can be essentially infinite, for our purposes, we will create a relatively small domain. The ellipsis … indicates that all numbers in between 3 and 9 are included in the domain. The limit is the value that y approaches as x approaches a given value.

In our domain, 9 is the highest value x can be. So, the limit of our function is the value of y as x gets closer to 9. The limit allows you to define the pattern of values for y that you can extrapolate for any possible value of x. Since those numbers can be broken down infinitesimally small, using an interval notation gives you a way to include all of those numbers without having to write them all out. A closed interval is expressed as [a, b] which is a set of all numbers between a and b, including a and b themselves.

An open interval is expressed using parenthesis instead of brackets, a, b. That is a set of all numbers between a and b, NOT including a and b themselves.

Derivatives are a special type of function that calculates the rate of change of something. Expressed in a graph, derivatives are the calculation of the slope of a curved line. Finding the derivative of a polynomial would be very tedious using limits and the slope formula.

However, there is another way to calculate the derivative of polynomials. Then we reduce the exponent by 1. We ended up with — 5 x 0 in the second term of the function by assuming the exponent in -5x could be written as -5x 1 , so we multiply it by the coefficient in front of the x, which is Following the same procedure as before, we start with 3x 1.

Multiplying the exponent by the coefficient, then reducing the exponent by 1, leaves us with 3x 0. Once the zero comes down, we end up with 0 as our third term.

The original function we started with was quadratic, but the derivative we ended up with is linear. The derivative will always be one degree less than the original function.

We hope our basic guide to differential calculus has provided you with a solid foundation to build from in your class. Calculus can be a very rewarding subject to learn because it has so many applications in the real world. And if you have any interest in physics or other sciences, calculus will go with it hand in hand!

Now that you armed yourself with all of this information, you should have no problem jumping into calculus head-first. Functions are used to describe mathematical things and can be difficult to define. The basic definition of a function can be said to be — a collection of ordered pairs of things, where the first members are fundamentally different in the pairs.

Functions usually have alphabetical letter as their names. The entire set of first numbers in the function is called a domain and the first members are called arguments. In this particular example, the domain has 5 numbers and the numbers 1, 2, 3, 4 and 5 are the arguments of the function.

The whole set of second numbers in the function is called the range and the second members are called the values. Going back to the above function, the range also has 5 numbers and the numbers 2, 4, 6, 8 and 10 are the values of the function. As mentioned before, the standard naming of a function is f. Thus we can explain this function in a sentence as follows:. The value of the function f at argument 1 is 2, its value at argument 2 is 4, its value at argument 3 is 6, its value at argument 4 is 8 and its value at argument 5 is Therefore a function can also be defined as a set of assigned values the second numbers to arguments the first numbers.

The linear function is the basic and essential function, on which calculus is based upon. This is a function that has a straight line running through the domain of its graphs. Such a line can be determined by two points that lie on it. It is possible to determine the linear function for the two values mentioned above by using the following formula. The y-intercept is the point at which the line passes the y-axis. If you did think that, please know that I am, as you read this sentence, smiling approvingly and giving you polite golf applause for your clever pun.

However, this problem is all about definite integrals, so there is no time for joking around. Steel yourself for the battle of your life! Attack this problem with your bear hands! But please, before you do, I would like the polite golf applause reciprocated. Sections of this page. Email or Phone Password Forgot account? See more of Calculus-Help on Facebook.

Mr Biologist Public Figure. Math Problem Solved City. Grey's Anatomy Humor Entertainment Website. Known as the study of change and motion, core calculus concepts include limits, derivatives, and integrals of functions. One of the first topics introduced in any calculus class, limits introduce the component of infinity to math problems.

How do you find the limit of a function? This lesson defines limits and provides a variety of examples to understand the concept. The process of finding the derivative of a function at any point is called differentiation, and differential calculus is the field that studies this process.

This overview of differential calculus introduces different concepts of the derivative and walks you through example problems. Integral calculus involves the concept of integration. Alongside differentiation, integration is one of the main operations in calculus.

Calculus has the reputation of being one of the most challenging subjects in school, even when compared with other advanced math classes. That’s because calculus is usually the first exposure students get to a version of math that requires more than just memorization to succeed.
