$H (t) = 12 + 7.9 \sin (\frac{2 π}{365} \cdot (76 - 76))$

Step 1

Subtract $76$ from $76$ .

$H (t) = 12 + 7.9 \sin (\frac{2 π}{365} \cdot 0)$

Step 2

Multiply $\frac{2 π}{365}$ by $0$ .

$H (t) = 12 + 7.9 \sin (0)$

Step 3

The exact value of $\sin (0)$ is $0$ .

$H (t) = 12 + 7.9 \cdot 0$

Step 4

Multiply $7.9$ by $0$ .

$H (t) = 12 + 0$

Step 5

Add $12$ and $0$ .

$H (t) = 12$
