Same as anywhere: opposite to a clock's conventional rotation. Mathematicians like to put x = 0º on the x-axis (so y = Sin x = 0) and measure anticlockwise from there.

The main kinds are plane trigonometry and solid trigonometry. The latter will include trigonometry in hyper-spaces.
Hipparchus is the father of trigonometry.
Trigonometry based on a unit circle and radians and trigonometry based on a right triangle.

anticlockwise
the clock ran anticlockwise
anticlockwise. (All toilets in the Northern Hemisphere flush clockwise, all toilets in Southern Hemisphere flush anticlockwise.)

Yes it can be (anticlockwise rotation).It means the same as counter-clockwise, and is also used as an adverb.

Plane trigonometry is trigonometry carried out in (on) a plane. This could be contrasted with spherical trigonometry, which is trigonometry carried out on the surface of a sphere. Certainly there are some other more complex forms of trig.
Trigonometry is applied in construction and building, as trigonometry measures right angled triangles.
