Hi @amoeba just wanted to check in if you had a chance to review this commit. The test failure is very strange (on an encryption test?!), but I can look into it! |
This test is known to be flaky (#43057), the failure is unrelated to the changes in this PR. |

Rationale for this change
Hyperbolic trigonometric functions are a common transformation for dealing with skewed data. And they are built into the core C++ libraries so require minimal change.
What changes are included in this PR?
Adding
a?(sin|cos|tan)hto the base C++ library and substrait and tests for these functions in pyarrow.Are these changes tested?
Yes, in the same style as the trigonometric functions.
Are there any user-facing changes?
Yes. Additional compute functions are added.
