Question 963649
.
Trigonometry-basics/963649: Please solve this equation exactly.
sin(arccos(3/5) - arctan(5/12)) =
~~~~~~~~~~~~~~~~~~~~~~~~~~



As worded/printed/presented in the post, the problem makes no sense and can not be solved/answered as requested.


The first term is a dimensionless real rational number, while the second term is the angle measure (in radians or in degrees).


So, it makes no sense to perform arithmetic operations on these numbers/expressions.



To the reader: ignore this post, since it is nonsense.



Ignore the "solution" by  @lwsshak3, since it is nonsense, too.



Keep in mind, that the computer code, which @lwsshar3 uses in his "solutions", is not able
to distinct nonsense from sense, so it simply deceives you in this case, instead of making an accurate analysis.
