$\frac{1}{4} \cdot \cos (200^{0} i) + \frac{1}{4} \cdot \sin (200^{0} j)$

Step 1

Anything raised to $0$ is $1$ .

$\frac{1}{4} \cdot \cos (1 i) + \frac{1}{4} \cdot \sin (200^{0} j)$

Step 2

Multiply $i$ by $1$ .

$\frac{1}{4} \cdot \cos (i) + \frac{1}{4} \cdot \sin (200^{0} j)$

Step 3

Combine $\frac{1}{4}$ and $\cos (i)$ .

$\frac{\cos (i)}{4} + \frac{1}{4} \cdot \sin (200^{0} j)$

Step 4

Anything raised to $0$ is $1$ .

$\frac{\cos (i)}{4} + \frac{1}{4} \cdot \sin (1 j)$

Step 5

Multiply $j$ by $1$ .

$\frac{\cos (i)}{4} + \frac{1}{4} \cdot \sin (j)$

Step 6

Combine $\frac{1}{4}$ and $\sin (j)$ .

$\frac{\cos (i)}{4} + \frac{\sin (j)}{4}$
