Does sin180+sin45=sin225? - Socratic
Nov 25, 2016 · So the #sin 180# is a certain value and the #sin45# is a certain value. The #sin 225# is also a separate certain value. You cannot find the #sin# of two different values, and add them up to be the #sin# of their sum. Think of it this way: #sqrt4 + sqrt25 = sqrt29# #2+5=sqrt29# #7cancel(=)sqrt29# In the same idea, #sin# does not work that way.
