Question

what is equation of slope of tangent ????​

Answer 1

Answer:

Figure out the slope of the tangent line. This is m=f′(a)=limx→af(x)−f(a)x−a=limh→0f(a+h)−f(a)h. Use the point-slope formula y−y0=m(x−x0) to get the equation of the line: y−f(a)=m(x−a).

Answer 2

Figure out the slope of the tangent line. This is m=f′(a)=limx→af(x)−f(a)x−a=limh→0f(a+h)−f(a)h. Use the point-slope formula y−y0=m(x−x0) to get the equation of the line: y−f(a)=m(x−a).
