A LITTLE CALCULUS is a collection of more than 70 interactive topics from a first year calculus course. To be used by both teachers and students, this app is designed to aid in the teaching and learning of calculus and should serve as a nice supplement to any introductory calculus textbook. Can be used to numerically and/or graphically verify computations for a wide variety of problems. Ultimately, the purpose of this app is to interact with and to gain a conceptual understanding of the fundamental topics of calculus. TOPICS: • Graph functions of one variable, as well as parametric and polar curves. • Investigate precalculus topics such as the equation of a line, graphing polynomials, Pythagorean Theorem, trigonometric functions, etc. • Understand the fundamental notion of a limit from a formal or informal point of view. • Study rates of change using the ideas from differential calculus (e.g., secant and tangent lines, derivatives, Mean Value Theorem, Newton's method, etc.) • Calculate the area of a region or surface, length of a curve, and volume of a solid using the techniques of integral calculus. • Interact with parametric and polar curves (e.g., slopes, areas, arc lengths, etc.) • Learn about sequences and series (geometric, harmonic, alternating, etc.) and approximate functions using Taylor polynomials. • Future releases to include more features, topics, and background information on each topic. FEATURES: • Customize each topic by changing any function, variable, and/or interval and by selecting from a variety of options. • Save current settings for each topic under the Options menu for easy retrieval. • Interact with every graph (drag to change the value of a variable or to move/rotate the graph, pinch to zoom, etc.) • Universal App (requires iOS 10 or later running on iPad, iPhone, or iPod Touch.) • Fully functional, built-in calculator. • No internet required, except for initial download and updates. • No in-app purchases or advertising. ## Key features - Interactive calculus topics - Graphical and numerical verification - Precalculus review - Differential and integral calculus - Sequences and series - Customizable topic settings - Interactive graphs ## Recent user reviews (10 of 20) All indexed reviews: https://appshunter.io/ios/app/a-little-calculus/id631866056/reviews.md ### 5/5 — Great !! *2019-12-03* Awesome calculus App!! ### 5/5 — Awesomenesssss! *2018-04-03* This is such a great app for learning maths concepts! I would give it 6 star if I could! Thank you so much for this awesome app! Keep up the great work ### 3/5 — Incorrect math? *2018-02-25* Why is the domain for x^1/3 greater than or equal to zero? It claims in the graph and the calculator windows non real values for negative domain. **Developer response:** Dear Krissy, Thank you for your review. Regarding power functions, since any exponent can be entered, the power function x^y is only defined for positive values of x. Many calculators behave the same way and for that reason, also include a dedicated cube root function, that can handle negative values of x as well. This same functionality is included in the app. While in the app's calculator, locate the x^3 button, and then click on "INV" or "INVERSES" to reveal the cube root (cbrt) button. In the next update, I will work on a solution so that the app will behave more the way you expected. Best, David ### 5/5 — Little calculis *2017-10-25* Brilliant beautiful breathes,XAM ### 5/5 — What I've been looking for! *2017-02-11* Thank you so very much! This is incredibly enlightening, just amazing. You have done a super job. WOW ### 5/5 — Love this!! *2016-06-30* Love this app ESP for integration problems. I have not found a better app. ### 1/5 — Crashes on 6+ *2015-06-03* M ### 5/5 — Just excellent! *2015-01-25* I noticed that my review has disappeared for some reason. I won't make this one long, but suffice it to say that I've returned to the reviews section of this app just to make sure it's getting a lot of five star ratings! It seriously deserves to show up as a five star app in the App Store. ### 5/5 — AMAZING *2015-01-20* I've been looking for the ability to have ways to help students visualize mathematics and this app has it all. It is flexible and cusomizable. Viewing objects from any angle when in 3-D is great and very powerful for students, teachers, and anyone learning calculus. ### 5/5 — Teacher created, student centered design *2015-01-20* A Little Calc is ideal for any math teacher to visually enhance mathematical concepts and promote higher level thinking in the classroom. Students will find a valuable resource in this app which includes a really wide range of useful topics. Buy it for yourself, buy it for your class. You won't regret it. ## Frequently asked questions about A Little Calculus ### What is A Little Calculus?
