10.2.10 Transforming arcsin into arctan
The asin2atan command
transforms arc sines in an expression to arc tangents by
using the identity
arcsin(x)=arctan | ⎛
⎜
⎜
⎜
⎜
⎝ | | ⎞
⎟
⎟
⎟
⎟
⎠ | . |
-
asin2atan takes
expr, an expression containing inverse trigonometric functions.
- asin2atan(expr) returns
expr with all instances of asin replaced according to the above formula.
