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 (open or closed), (open or closed). Write "pi", "F" or "-F" to designate , or .
