9.2.7 Transforming arccos into arcsin
The acos2asin command
transforms any acoss in an expression to asins,
using the identity arccos(x)=π/2−arcsin(x).
-
acos2asin takes
expr, an expression containing inverse trigonometric functions.
- acos2asin(expr) returns
expr with any acoss replaced by the appropriate asins.
Example
acos2asin(acos(x)+asin(x)) |
Output (after simplification):
