Wpisz x i y, aby otrzymać r i θ.
Wpisz r i θ, aby otrzymać x i y.
Wskazówka: Jeśli θ jest w radianach, przełącz tryb kąta powyżej.
Dla punktu (x, y) promień biegunowy wynosi r = √(x² + y²) , a kąt wynosi θ = atan2(y, x) . atan2 zapewnia poprawną ćwiartkę i bezpiecznie obsługuje x = 0.
deg = rad × (180/π),
rad = deg × (π/180) x = r·cos(θ),
y = r·sin(θ) Explore our complete collection of SEO software, AI tools, business applications, calculators and converters designed to streamline engineering, math, and digital growth.
