Question 818890
Your mention of alpha and beta lead me to believe that your equation is:
{{{ 4sin(x-8)=5sin(x-4) }}}
and not what you posted (which is equivalent to):
{{{ 4sin(x)-8=5sin(x)-4 }}}
Either way, please put arguments to functions in parentheses like you see above. Problems that are unclear are less likely to get a quick response.<br>
Please re-post your question.
