Trigonometric Functions
All major trignometric functions are built in to the function grapher. You may use it freely in your graphs. The following trigonometric functions are supported:
| function | name | examples |
|---|---|---|
| sin | sine | sin(x), sin(x+pi), sin(1/x) |
| cos | cosine | cos(x), x^2+cos(x^2), cos(1/x+2*pi), |
| tan, tg | tangent | 7+tan(x), tan(x+3), tan(cos(x)) |
| cot, ctg | contangent | cot(x), 1/cot(x) |
| sec | secant | sec(x) |
| csc | cosecant | csc(x) |

Inverse Trigonometric Functions
Trigonometric functions are periodic and as such, their inverse domain must, sometimes, be restricted. For example 'asin' is the inverse of the sine function which has a period of 2 pi and it ranges between -1 and 1, asin is defined of between -1 and 1 and its principal branch between -pi/2 and pi/2.
| function | name | examples |
|---|---|---|
| asin, arcsin | arcsine | asin(x), asin(sin(x)) |
| acos, arccos | arccosine | acos(x), acos(cos(x)), cos(1/x) |
| atan, arctan, arctg, atg | arctangent | atan(x), atan(tan(x)), atan(x*pi/2), atan(1/x) |
| acot, arccot, arcctg, actg | arccotangent | acot(x) |
| asec, arcsec | arcsecant | asec(x) |
| acsc, arccsc | arccossecant | acsc(x) |
