Defintion
- y = sin(x) : sine curve
- Period = 2*pi.
- Amplitude = 1. Range is between -1 and 1
- sin(0) = 0, sin(90) = 1, sin(180) = 0 and sin(270) = -1.
- y = cos(x) : cosine curve
- Period = 2*pi.
- Amplitude = 1. Range is between -1 and 1
- cos(0) = 1, cos(90) = 0, cos(180) = -1 and sin(270) = 0.
- y = tan(x) : tangent curve.
- Period = pi.
- Range is between -infinite to +infinite
- tan(0) = 0, tan(89.9999999) = 9999999, tan(90.0000001) = -9999999.
- y = csc(x) : cosecant curve.
- Period = 2*pi.
- Range is less than -1 and greater than 1.
- csc(0) = 9999999, csc(90) = 1, csc(180) = 9999999 and sin(270) = -1.
- y = sec(x) : secant curve
- Period = 2*pi.
- Range is less than -1 and greater than 1.
- sec(0) = 1, sec(90) = 9999999, sec(180) = -1 and sin(270) = -9999999.
- y = cot(x) : cotangent curve
- Period = pi.
- Range is between -infinite to +infinite
- cot(0) = 9999999, cot(90) = 0, tan(180) = -9999999.
