Trigonometry
- Secant, Cosecant and cotangent
- Sec (x) = 1 / cos (x)
- sec (280) = 1 / (cos(280)) = 5.76
- Cosec (x) = 1 / sin (x)
- cosec (360) = 1 / (sin(360)) = 1.04
- Cot (x) = 1 / tan (x)
- cot (115) = 1 / (tan(115)) = -0.466
- 1 + tan²(x) = sec²(x)
- 1 + cot²(x) = cosec²(x)
- inverse functions
- cot(x) = cos(x) / sin(x)
