Inverse Trigonometry
Inverse Trig
The study of the inverses of the
six trig functions.
Technical note: Since none of the six trig
functions sine, cosine, tangent, cosecant, secant,
and cotangent are onetoone,
their inverses are not functions.
Each trig function can
have its domain restricted,
however, in order to make its inverse a function. Some mathematicians
write these restricted trig functions and their inverses with
an initial capital letter (e.g. Cos or Cos^{1}).
However, most mathematicians do not follow this practice. This
website does not distinguish between capitalized and uncapitalized
trig functions.
