Trig Solver vs Perfboard Lab

Trigonify brings the core tools for learning trigonometry into one focused, visual workspace. Solve a triangle, explore the unit circle, graph a function, review formulas, and practice the ideas behind each answer—without creating an account or seeing ads. SOLVE WITH STEPS • Solve right triangles with SOHCAHTOA and the Pythagorean theorem • Find missing sides and angles with clear worked steps • Use inverse sine, cosine, and tangent with domain guidance • Switch between degrees, radians, gradians, and DMS • Save solutions and return to them later SEE HOW TRIG FITS TOGETHER • Drag around an interactive unit circle • View exact values, quadrants, and reference angles • Graph sine, cosine, and tangent with live controls for amplitude, period, phase, and vertical shift • Link a moving unit-circle point to its waveform in the phase-shift playground STUDY AND PRACTICE • Search a structured trigonometry formula reference • Favorite the identities you use most • Practice by topic, review mistakes, and track streaks and accuracy • Use Exam Mode to hide solvers and answers while keeping reference tools available BUILT FOR REAL STUDY • No account required • No advertising • Light, dark, high-contrast, and reduced-motion options • iPhone and iPad support • Local app settings, favorites, history, and practice progress Trigonify is an educational calculator and study aid. Check results before using them for exams, grading, engineering, construction, financial, or safety-critical work. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Understand electronics by trying it out: Perfboard Lab turns your iPhone, iPad or Mac 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 voltage source, current source, solar module 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 • Sensors: photoresistor, NTC and PTC, with the brightness taken from the camera if you like 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 hookup 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 starts with an LED that burns out and shows you how to find the right series resistor • A free task at your level every day: build, complete, adjust or rescue, with a time limit without Perfboard Lab Pro • AI-assisted tasks that suit your level and explanations step by step on the board (Perfboard Lab Pro) • Lots of ready-made examples: from an LED with a series resistor to logic circuits, transistors and op-amps • The formula collection 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 • In many languages and usable with VoiceOver, Voice Control and Apple Pencil • No ads, no tracking FREE The perfboard with almost all parts and their examples, the daily task, text labels, the instruments and the simulation are free. A circuit can have up to 7 parts. PERFBOARD LAB PRO With “Perfboard Lab Pro” you save as many circuits as you like and keep working 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, current source, solar module and the sensors with their examples, the stripboard and the breadboard with their examples, AI-assisted tasks and explanations, and the 3D view. • Perfboard Lab Pro is available as a subscription (yearly, monthly, weekly). The App Store shows the prices before you buy. • A subscription renews automatically 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
