According to Maple, the answer is: 1/12 (cos (3x + 2)). 3 sin (3x +2)+1/8 cos (3x + 2) sin (3x +2)+3/8x + 1/4. But ... May 13, 2015 ... The problem is: lim x->0 of (tan7x)/(sin3x) I know that lim x->0 (sinx)/x = 1, but I don't really know how to apply that here. (-9A (os 3x-98 Sin 3x)+4(-3A Sin 3x + 3B Cos3x). + 4 CA Cos 3x + B Sin 3x). = [-5A ]. T-5. +12B Cos 3x + -12A-5B Sin3x= Sin 3x. Nov 2, 2016 ... sin(3x) + sin(x) = sin(2x + x) + sin(2x - x) = [sin(2x)*cos(x) + sin(x)*cos(2x)] + [sin(2x)*cos(x) - I have found the correct answer by using the golden ratio, but how to get the answer from the first part I do not know. I thought that this would be a simple ... 1+ sin 3x. SECTION 102. 0
