Solve 2.1u+2.2u

$$2.1 u + 2.2 u$$

Differentiate w.r.t. u

$$4.3$$

Steps Using Definition of a Derivative

Combine 2.1u and 2.2u to get 4.3u.

$$\frac{\mathrm{d}}{\mathrm{d}u}(4.3u)$$

The derivative of ax^{n} is nax^{n-1}.

$$4.3u^{1-1}$$

Subtract 1 from 1.

$$4.3u^{0}$$

For any term t except 0, t^{0}=1.

$$4.3\times 1$$

For any term t, t\times 1=t and 1t=t.

$$4.3$$

Evaluate

$$\frac{43u}{10}$$

Solution Steps

Combine 2.1u and 2.2u to get 4.3u.

$$4.3u$$
