Question

We know W = F×S, let this be the equation 1; Also dW = F×dS
But if we differentiate equation 1,
by the product-rule dW = d(F×S) = F×dS+S×dF
So where does this S×dF term go?

Answer 1

Answer:

Chain Rule for One Independent Variable

Suppose that x=g(t) and y=h(t) are differentiable functions of t and z=f(x,y) is a differentiable function of xandy. Then z=f(x(t),y(t)) is a differentiable function of t and

where the ordinary derivatives are evaluated at t and the partial derivatives are evaluated at (x,y).

Answer 2

Explanation:

There are 4 basic types of tissue: connective tissue, epithelial tissue, muscle tissue, and nervous tissue. Connective tissue supports other tissues and binds them together (bone, blood, and lymph tissues). Epithelial tissue provides a covering (skin, the linings of the various passages inside the body).
