r এবং θ পেতে x ও y লিখুন।
x এবং y পেতে r ও θ লিখুন।
টিপ: যদি θ রেডিয়ানে হয়, উপরে Angle মোড বদলান।
বিন্দু (x, y) এর জন্য মেরু ব্যাসার্ধ হলো r = √(x² + y²) এবং কোণ হলো θ = atan2(y, x) । atan2 সঠিক চতুর্ভুজ নিশ্চিত করে এবং x = 0 নিরাপদে সামলায়।
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.
