With the default interval policies, transcendental functions are not
enabled since they usually do not provide the inclusion property of
interval arithmetic. This is why you get a compile-time error.

For specific policies, you can take a look at the find_root.cpp and
transc.cpp examples. The first one provides non-guaranteed interval
functions by relying on the standard library. The second one provides
guaranteed interval functions by relying on an external library.
