vs Photomath
Backrow handles problems that don't fit a phone camera — pasted text, LaTeX, file uploads — and works on desktop.
Frequently asked questions
Do I need an account to use Trigonometry Solver?+
Yes — Trigonometry Solver calls an AI model, so it needs a free account. Signing up takes a minute, needs no card, and starts you with 200 credits. 14 of Backrow's calculators do run with no account at all; they are listed at backrow.ai/free.
Is Trigonometry Solver actually free?+
Yes — Trigonometry Solver is covered by the welcome gift. Every new Backrow account starts with 200 credits, one time, and Trigonometry Solver runs at zero credit cost. No card required to sign up.
How is this different from Wolfram Alpha?+
Wolfram Alpha is a great single-purpose tool. Backrow's Trigonometry Solver is one of 120+ tools in a single platform — alongside lecture recording, AI notes, flashcards, quizzes, and study guides. You stop juggling five subscriptions and switching tabs.
Will my professor catch me using this?+
Trigonometry Solver is a study aid, not a cheating tool. Use it the same way you'd use a calculator, dictionary, or office hours: to understand the work, not to dodge it. For assignments where AI is explicitly banned, don't use it. For everything else (problem sets, exam prep, learning a topic faster), it's fair game.
Do I need to download anything?+
No. Trigonometry Solver runs in your browser. Works on Mac, Windows, Linux, iOS, and Android. There's also a mobile-installable version (PWA) at backrow.ai if you want it on your home screen.
What other mathematics tools does Backrow have?+
Backrow's Math engine includes everything from problem solvers to trigonometry tools. See the full Math catalog at backrow.ai/free or browse all 120 tools at backrow.ai/free.
Can I use Trigonometry Solver on my phone?+
Yes — Trigonometry Solver works in any modern mobile browser (Safari on iOS, Chrome on Android). The interface is touch-optimized for small screens.
