OEF Inverse trigonometric functions
--- Introduction ---
This module actually contains 10 exercises on inverse trigonometric
functions:
arccos, arcsin, arctg, et leurs compositions.
arccos(cos)
Compute
, writing it under the form
, where
and
are rational numbers.
Linear arccos(cos)
For
within the interval [,], one can simplify the function
defined by
to a linear function of the form
. What is this linear function? Write pi for
.
Definition domain (Arcsin, Arccos)
Let
be the function defined by
.
The definition domain of
is composed of
disjoint intervals.
The definition domain is the reunion of intervals : What are their bounds (in increasing order)
,
,
.
If a bound is infinity, write +inf or -inf
arccos(sin)
Compute
, writing it under the form
, where
and
are rational numbers.
arctg(tg)
Compute
, writing it under the form
, where
and
are rational numbers.
Composed differentiability
Is the function
definded by
differentiable in the interval [,] ?
Composed range
Consider the function
defined by
. Determine the (maximal) interval of definition
and the image interval
of . To give your reply, let
