WebD: 1 and 3 only. Let f be a differentiable function. If h (x)= (1+f (3x))2, which of the following gives a correct process for finding h′ (x) ? D: h′ (x)=2 (1+f (3x))⋅f′ (3x)⋅3. What is the slope of the line tangent to the curve y3−xy2+x3=5 at the point (1,2) ? B: 1/8. If sin (x+y)=3x−2y, then dydx=. D: 3−cos (x+y)/2+cos (x+y ... WebUsing angle sum formula: d d x sin ( x) = lim h → 0 sin ( x) cos ( h) + cos ( x) sin ( h) − sin ( x) h. Rearranging the terms: d d x sin ( x) = lim h → 0 cos ( h) sin ( h) − sin ( x) + sin ( x) cos ( h) h. Factoring out sin ( x) from the last two terms:
