Math Wiki vs Perfboard Lab

"What is a linear function?", "How to solve a quadratic equation?", "What is the Pythagorean theorem all about?" Math Wiki provides numerous exercises and articles in the field of mathematics, which are helpful to better understand the foundations of mathematics from 7th grade upwards. The app is also useful in preparation for middle school exams, high school and college math. Math Wiki includes the following features: • portable and compact reference work for math • glossary of mathematical terms • numerous foundations from 7th grade • ideal for learning, reference and practice • simple and detailed explanations with lots of examples for better understanding • exercises on every topic • clear structuring with subtopics • search option • suitable for high school graduation and middle school exams Math Wiki has many explanations of important topics of mathematics which are described in detail. In addition to the explanations there are examples and lots of tasks with solutions. Learn, repeat or practice math anytime and anywhere with our wiki and encyclopedia of mathematics. The following topics are already included: Arithmetic / laws of arithmetic / mathematical rules • Elementary arithmetic • Fractions • Percentage calculation • Brackets • Exponents and roots • Logarithms Geometry • Geometric formulas • Pythagorean theorem • Trigonometry Equations • Fractional equations • Linear equations • Quadratic equations • Systems of linear equations • Solve equations Functions • Linear functions • Quadratic functions • Sine and cosine • Trigonometric functions • Exponential functions • Growth and decay • Real functions • Exponential functions • Rational functions • Family of curves Stochastic • Random experiments and events • Probability • Calculating probability • Tree diagrams • Combinatorics • Statistics Differential calculus • Differentiability and derivative • Derivative rules • Applying the derivative • Curve sketching • Applications of differential calculus Integral calculus • Indefinite integral • Integration rules • Definite integrals • Calculating areas with integrals • Applications of integral calculus Analytical geometry • Vectors • Vector algebra • Lines in three dimensions • Relative position of lines • Planes • Relative position of planes For more information about our terms and policies please visit: https://www.lakdev.de/en/terms We strive to constantly expand the app and add new items and tasks.

Understand electronics by trying it out: Perfboard Lab turns your iPhone, iPad or Mac with Apple silicon into an electronics lab. Build a circuit and switch on the power. Right away you see what happens: LEDs light up, buzzers beep, motors turn and hum. And if your maths was off: it smokes, it sparks and the part burns out – without any real damage. SEE WHAT HAPPENS, INSTANTLY • Every change is computed instantly with real physics • Overloaded parts smoke in four levels until they burn out • The analysis explains in plain words what is wrong: an LED the wrong way round, a missing series resistor, a short circuit, an open circuit MEASURE LIKE IN A REAL LAB • Multimeter: voltage, current and power at every part • Oscilloscope: voltage and current over time OVER 20 REAL PARTS • DC voltage source, AC source, current source and breadboard power supply • Resistors, potentiometers, ceramic and electrolytic capacitors, inductors, switches • Diodes and Zener diodes, NPN and PNP transistors, N- and P-channel MOSFETs, relays, op-amps, voltage regulators and Timer NE555 • LEDs in six colours, an incandescent lamp, a buzzer with a real tone and a motor whose hum matches its turning • Real characteristics as in a parts catalogue, each with a short explanation JUST LIKE ON THE WORKBENCH • Draw wires with the pen – straight wires with bends and branches • Perfboard, with Perfboard Lab Pro also stripboard with cuttable strips and breadboard as used with Arduino • Copy parts with all their values; text labels annotate your circuit • Real 2.54 mm grid: what fits in the app fits on the real board • Bill of materials with every part and the length of every wire • With Perfboard Lab Pro you see your circuit in the 3D view: real parts on the board that you turn, tilt and measure PERFECT FOR SCHOOL AND CLASS • A guided tutorial builds your first circuit with you • AI-assisted tasks and explanations in Perfboard Lab Pro: tasks that suit your level, explanations step by step on the board. • Lots of ready-made examples: from an LED with a series resistor to logic circuits, transistors and op-amps • The interactive formula collection adapts to your circuit: with the power on, every worked example calculates with the measured values of your parts and shows where each number comes from. • Teachers pass their default settings on to the whole class as a file FOR EVERYONE • For iPhone, iPad and Macs with Apple silicon • In many languages and usable with VoiceOver and Voice Control • No ads, no tracking FREE The perfboard with almost all parts and their examples, text labels, the instruments and the simulation are free. A circuit can have up to 7 parts. Your circuit is kept automatically. PERFBOARD LAB PRO With “Perfboard Lab Pro” you save as many circuits as you like and keep working on the same circuit on iPhone, iPad and Mac. You export them as PDF with a bill of materials and share them with others. Plus circuits with more than 7 parts, op-amp, voltage regulator, Timer NE555, motor, Zener diode and current source with their examples, the stripboard and the breadboard with their examples, AI-assisted tasks and explanations, and the 3D view. • Try it free for 3 days, then a weekly subscription. The App Store shows the price in your currency before you buy. • The subscription renews automatically every week unless it is cancelled at least 24 hours before the end of the period. Payment is charged to your Apple Account. You can cancel at any time in your Apple Account settings under “Subscriptions”. • Terms of use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ • Privacy policy: https://pascalschroeer.github.io/PerfboardLab_PrivacyPolicy/ Legal notice: https://pascalschroeer.github.io/PerfboardLab_PrivacyPolicy/#legal-notice
