Trigonometry calculators for right-angled triangles and beyond. Use SOHCAHTOA to find missing sides and angles, calculate sin/cos/tan of any angle, convert between degrees and radians, and work with bearings. Every result includes the complete step-by-step working used in exams.

Unlike calculators that show only the final answer, every Pythagorist tool displays the complete method — the same working you would write in an exam. This means you can understand the process, not just copy a number. Students who understand the method score more marks, because examiners award points for correct working even when the final answer contains an arithmetic error.
