expand 1/2 sin(2(x+t))+1/2 sin(2(x-t))

expand

\frac{1}{2} sin (2 (x + t)) + \frac{1}{2} sin (2 (x - t))

\frac{1}{2} sin (2 x + 2 t) + \frac{1}{2} sin (2 x - 2 t)

Solution steps

\frac{1}{2} sin (2 (x + t)) + \frac{1}{2} sin (2 (x - t))

Expand

2 (x + t) : 2 x + 2 t

= \frac{1}{2} sin (2 x + 2 t) + \frac{1}{2} sin (2 (x - t))

Expand

2 (x - t) : 2 x - 2 t

= \frac{1}{2} sin (2 x + 2 t) + \frac{1}{2} sin (2 x - 2 t)

(19417600 = 6000000 \cdot t + 46000000) \cdot 0.0269

- 5 (x + 3 y = 13)

(y = 2,) (x = + 1)

\frac{16 + 6 s ^{2}}{s ^{2} ( s + 4 )}
