Solve -3a-4s+4a+4s=

$$- 3 a - 4 s + 4 a + 4 s =$$

Evaluate

$$a$$

Solution Steps

Combine -3a and 4a to get a.

$$a-4s+4s$$

Combine -4s and 4s to get 0.

$$a$$

Differentiate w.r.t. a

$$1$$

Steps Using Definition of a Derivative

Combine -3a and 4a to get a.

$$\frac{\mathrm{d}}{\mathrm{d}a}(a-4s+4s)$$

Combine -4s and 4s to get 0.

$$\frac{\mathrm{d}}{\mathrm{d}a}(a)$$

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

$$a^{1-1}$$

Subtract 1 from 1.

$$a^{0}$$

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

$$1$$
