Supplied Functions (Trigonometric) ☆☆☆

SIN(x) | The sine of x
COS(x) | The cosine of x
TAN(x) | The tangent of x
CSC(x) | The cosecant of x , 1/sin(x)
SEC(x) | The secant of x , 1/cos(x)
COT(x) | The cotangent of x , 1/tan(x)
ASIN(x) | The arcsine of x, the angle θ such that sinθ=x, where －π/2≦θ≦π/2
ACOS(x) | The arccosine of x , the angle θ such that cosθ＝x, where 0≦θ≦π
ATN(x) | The arctangent of x , the angle θ such that tanθ＝x, where －π/2＜θ＜π/2
ANGLE(x,y) | The angle between the positive x-axis and the vector joining the origin to (x,y). where －π＜ANGLE(x,y)≦π

<Note> If OPTION ANGLE DEGREES is in effect, the angles about these functions are in degrees.

<Note> These functions can not be used in the RATIONAL operation mode. See Precision options menu
