SOLUTION: VERIFY sin(x+h)-sinx/h=cosx(sinh/h)+sinx(cosh-1/h) This is a Pre-Cal TRIG Identities section. I am stuck half ways and cant get past it. Any help would be greatly appreciated THA

Question 873196: VERIFY sin(x+h)-sinx/h=cosx(sinh/h)+sinx(cosh-1/h) This is a Pre-Cal TRIG Identities section. I am stuck half ways and cant get past it. Any help would be greatly appreciated THANKS PEACE!!! Let me know I can upload a picture of the problem if I confused anyone PEACE!!! Answer by richard1234(7193) (Show Source):
You can put this solution on YOUR website! First you may want to use the identity sin(x+h) = sin x cos h + cos x sin h. The rest is mostly just algebra.
