Question

if y=x/x+1 find dy/d​

Answer 1

Given:

• y=x/x+1

To find:

• dy/dx

Solution:

Do refer to the attachment.

Formula used:

• d(u/v)/dx = (u.dv/dx - v.du/dx) / v²
• dC/dx = 0
• dx/dx = 1

Other Formulas:

• ddx√x=12√x.
• ddx√f(x)=12√f(x)ddxf(x)=12√f(x)f′(x)
• ddxc⋅f(x)=cddxf(x)=c⋅f′(x)
• ddx[f(x)±g(x)]=ddxf(x)±ddxg(x)=f′(x)±g′(x)
