-Sin[\[Pi]/4 - 2 x]
How can I convert the trig function above into the equivalent form below?
Sin[-(\[Pi]/4) + 2 x]
The simplification approach below doesn't yield the desired result.
-Sin[\[Pi]/4 - 2 x] // FullSimplify
Interesting, the behaviour of Sin depends on the alphabetical order of the variables:
Sin
Sin[-a + b] Sin[-b + a] Sin[-(\[Pi]/4) + 2 a]
