Unit Circle: Trig Visualizer

Master the unit circle and trigonometry visually. Unit Circle: Trig Visualizer connects circle geometry, exact values, and trigonometric wave graphs into one interactive learning tool. INTERACTIVE UNIT CIRCLE - Drag the point smoothly around the 360-degree circle or jump directly to special angles (0°, 30°, 45°, 60°, 90°, and beyond). - Observe how cosine forms the horizontal coordinate and sine forms the vertical coordinate. - Follow the tangent projection on the vertical line at x = 1, with immediate feedback when tangent is undefined. - Switch between degrees and radians instantly with a single tap. SYNCHRONIZED TRIG GRAPHS - See sine, cosine, and tangent graphs update in real time as you adjust the angle. - Scrub smoothly across the first half-turn (0 to π) or toggle to the second half-turn (π to 2π). - Follow coordinates, wave crests, zeroes, and asymptotes side by side with the circle. SPECIAL ANGLES REFERENCE - Browse the full table of 17 standard unit circle angles from 0° to 360°. - Review exact simplified radical values for sin, cos, and tan in both degrees and radians. - Tap any angle in the reference list to inspect it on the unit circle. PRACTICE QUIZZES & MISTAKES REVIEW - Test your recall with focused 10-question quizzes covering exact values, degree-to-radian conversions, and quadrants. - Read worked step-by-step solutions and mathematical rules for every question. - Missed questions are saved to your review list so you can practice them again until mastered. DESIGNED FOR FOCUSED STUDY - Clean typography and clear color-coded trigonometric functions. - No user account or sign-in required. Your quiz progress and review list remain on your device.
