It is a powerful, high-quality graphing calculator that takes full advantage of the multitouch display and the powerful graphing capabilities of the iPad and iPhone, both in 2D and 3D. "The app you need to survive the next semester." -- Gizmodo A simple yet intuitive interface makes it easy to enter and/or edit equations and visualize them in mathematical notation. It's capable of displaying explicit and implicit (opt) equations as well as inequalities (opt) in both 2D and 3D, in all standard coordinate systems: cartesian, polar, spherical, and cylindrical, all with fantastic speed and beautiful results, which can be copied, emailed or saved to the photo library. It also includes an evaluation feature to evaluate equations at specific points and a library where you can store commonly used equations. Up to 6 equations can be visualized simultaneously in both 2D and 3D modes; this limitation can be removed by purchasing the advanced feature set. Features: - Enhanced 2D - 3D plotting mode for great hi-res graphics. - Adaptive 2D algorithms. - Hyperbolic and Inverse functions. - Functions such as Min, Max, if. - Configurable axis decimal / π - Independent 2D zoom - Support for cartesian, polar, cylindrical, and spherical coordinate systems. - Interactive expression evaluation. - Library for commonly used equations. - Swipe to delete equations from the equation list. - Save to photo library. - Copy to clipboard. - Turn graphs on/off - Drag to rotate - move. The advanced feature set gives you access to: - External screen support - 2D tracing. - 2D and 3D implicit graphs. - 2D and 3D inequalities. - Roots and Intersections (2D) - Value Table - More features to come!

Derivative calculator application helps you to evaluate functions through differentiation. It is a relatively complex topic of calculus and needs utmost understanding and grasp on the concept. But you can use the derivative app to solve and learn to do it yourself. This application can be your savior if you want to complete an assignment on short notice and or in any worst scenario. The differentiation calculator has many features that make it stand out the most among the other applications on the Apple app store. Before heading there, let’s see who can use it? Beginners: By using the differential calculator app to solve the function, any beginner to differentiation can have some practice which will later save them in their tests and exams season. Senior students: Those students who already understand derivatives can still make good use of this application. They can use it to solve their assignments or learn to evaluate any challenging question. Teachers: Yes, even teachers will find this calculator helpful. It can be used to check assignments or remove any ambiguity when you hit a dead end while differentiating. Anyone up for learning: Those who are not a student or teaching in some institute but just want to learn derivatives because they find them interesting (yeah many people love math). Similarly, math article writers can solve examples here which they want to add in their posts. Now, let’s see its top features. Multiple differentiation: You can differentiate the same function for first, second, third, fourth, and fifth derivatives. All you have to do is enter the number in the labeled box. Step-by-Step solution: Not only can you find the answer but this differentiation calculator gives you the complete solution which contains all the steps of the evaluation. This helps those users the most who don’t understand derivatives very much. Example function: This application can be used by any newbie, the one who faces difficulty in typing functions. The example functions can give them basic know-how in that regard. Plots: One plus point of downloading this particular derivative calculator is that you get a plot for almost every solved function. These were some of the many features. Lastly, we will tell you how to use this calculator. 1. Enter the function. Take help from examples if you have any confusion. 2. Choose the variable. 3. Enter the number of derivatives. 4. And click calculate. Hope you enjoy this app. Your feedback and suggestions are always welcome.
