Identidades Trigonom´etricas Fundamentales 1. csc(x) = 1 sin(x) 2. sec(x) = 1 cos(x) 3. tan(x) = sin(x) cos(x) 4. cot(x) = cos(x) tan(x) 5. 1 + tan2 (x) = sec2 (x) 6. 1 + cot2 (x) = csc2 (x) 7. sin(−x) = − sin(x) 8. cos(−x) = cos(x) 9. tan(−x) = − tan(x) 10. sin π 2 − x = cos(x) 11. cos π 2 − x = sin(x) 12. tan π 2 − x = cot(x)
