Mathematics with PocketCAS Pro vs Learn Python | PythonBook

PocketCAS is a graphing calculator and computer algebra system for iPhone and iPad. It graphs your functions, gives exact answers and shows the steps behind derivatives and integrals. Everything runs on your device, so it works without internet or an account, and you buy it once instead of paying for a subscription. Graphs - 2D plots of functions, implicit equations, polar and parametric curves, run charts and vector fields. PocketCAS marks zeros, extrema and intersections. In full screen, tap a mark to read its coordinates. - 3D surfaces and space curves with soft light and shading. Drag to turn them, pinch to zoom, add a floor grid or pick another color map. - Animated plots: use the variable anim in any plot. Suggestions and steps - Under each function, suggestions show what to look at next: its derivative, zeros, extrema, integral or a plot. The answer is already in the suggestion. Tap it to add it to your document. - Functions get a small plot right beside the result. - Calculation steps show the rules behind a derivative, an integral, a differential equation or an extremum, one row per rule. Exact answers - Algebra: solve equations and systems, simplify, expand and factor expressions, divide polynomials. - Calculus: limits, derivatives, integrals, Taylor series and sums. - Linear algebra: matrices, determinants, inverses, eigenvalues and eigenvectors. - Differential equations: ordinary differential equations, solved exactly. - Units and constants: enter physical formulas with units and convert the results. - Scripts: define your own functions with conditions, loops and recursion. Reads like your textbook - Results look the way they do in a textbook: fractions, roots, sums, integrals and matrices. Long results wrap to the width of your screen. - A math keyboard with every function in reach. Your recent functions sit above it, and a hint shows what goes between the brackets. Made for daily work - Documents keep your calculations and plots together, so you can pick up where you left off. - iCloud syncs your documents between iPhone, iPad and Mac. The Mac app is a separate purchase. - Export: print or share plots, entries or whole documents as PDF. - Import: reuse functions from other documents, or load data from CSV files. - Help built in: the reference explains every function with examples, and tutorials get you started. A free version of PocketCAS lets you try the interface and many features first. What users say "This program has an incredible amount of power for such a compact program. I teach high school math, and this program can work with all sorts of expressions, graphs, and help check my work. Definitely worth it!" "One of three Apps I use when teaching A Level maths. Have recommended to numerous students. Excellent." "This app is amazing and could help me with about 98% of the math that I had to do during my mechanical engineering degree all the way from my bachelor to my master." Questions or ideas?

Learn Python at your own pace with structured lessons, quizzes, and tools to keep your learning organized. Explore Python fundamentals, follow your progress, and return to the topics you want to study. Learn Python brings lessons, quiz questions, notes, and learning progress together in one place. Whether you're opening your first Python lesson or revisiting a topic, you can follow a clear chapter-based learning experience. EXPLORE PYTHON LESSONS Start with Python Introduction and work through lessons covering topics shown in the app, including: • What is Python? • Installing Python • Python IDEs • Hello World Program • Python File Structure • Syntax Basics • Python Comments Each lesson is presented within a chapter, with reading-time information and quiz questions. Move through the lesson list in an organized way and revisit individual topics whenever you need to. PRACTICE WITH QUIZZES Use the quiz questions associated with lessons to review what you've studied. The chapter overview displays quiz information alongside the lesson count, so you can see the learning material and practice opportunities together. FOLLOW YOUR LEARNING PROGRESS See how far you've progressed through a chapter with a completion percentage and progress bar. Lesson cards display individual progress, and completed lessons are clearly marked. A Continue Reading label helps you identify a lesson to return to. The chapter overview also brings together useful details such as completed lessons, quiz questions, and average reading time. Stay aware of what you've covered and what remains. KEEP YOUR STUDY MATERIAL ORGANIZED Take Notes Keep study notes accessible while working through your learning material. Bookmarked Lessons Return to lessons you've saved for later review. Recent Lessons Find recently studied lessons from your learning history. These tools make it easier to pick up where you left off and keep important topics within reach. EXPLORE THE CODE SECTION Access the app's Code section from the bottom navigation alongside Home, Search, Progress, Help, and Menu. Keep coding-related learning close to your lessons and study tools. SET UP YOUR LEARNING EXPERIENCE Make the app more comfortable to use with settings visible in the app: • Dark Mode for changing the appearance • App Language preferences • Adjustable Text Size • Notification settings • Learning Schedule for daily study goals and reminders Choose the preferences that suit your reading and study routine. LEARN IN A WAY THAT WORKS FOR YOU Python learning is easier to follow when lessons, practice, and progress are organized in one place. Open a chapter, read a topic, review quiz questions, and track completed lessons as you move forward. With Learn Python, you can explore introductory Python topics, keep notes, revisit bookmarks, and manage your learning schedule from a single app. CLEAR CHAPTER OVERVIEWS Before you open a lesson, the chapter header shows key details: chapter number, reading time, completed lessons, quiz questions, and overall progress. A separate summary highlights lesson and quiz totals and average reading time. LESSON-BY-LESSON TRACKING The lesson list keeps reading-time estimates, quiz counts, and progress percentages beside each topic. Completed lessons and lessons marked Continue Reading are easy to distinguish. STUDY AT YOUR OWN PACE Choose a lesson, return to bookmarked material, or open your notes while reviewing. Use the learning schedule to set study goals and reminders, and adjust text size or appearance to suit your preferences. FROM FIRST TOPICS TO REGULAR REVIEW Begin with introductory topics such as Python installation and your first Hello World program. Continue with file structure, syntax, and comments, then revisit what you've covered through quizzes and progress indicators. Start exploring Python lessons and make steady progress, one topic at a time.
