sin(10x)=sin(10(x+1))

Solución

sin (10 x) = sin (10 (x + 1))

Solución

x = - \frac{1}{2} + \frac{π}{20} + \frac{πn}{5}, x = - \frac{1}{2} + \frac{3 π}{20} + \frac{πn}{5}

Grados

x = - 19.64788 \dots^{\circ} + 3 6^{\circ} n, x = - 1.64788 \dots^{\circ} + 3 6^{\circ} n

sin (10 x) = sin (10 (x + 1))

Restar

sin (10 (x + 1))

de ambos lados

sin (10 x) - sin (10 (x + 1)) = 0

Re-escribir usando identidades trigonométricas

sin (10 x) - sin (10 (x + 1))

Utilizar la identidad suma-producto:

sin (s) - sin (t) = 2 sin (\frac{s - t}{2}) cos (\frac{s + t}{2})

= 2 sin (\frac{10 x - 10 ( x + 1 )}{2}) cos (\frac{10 x + 10 ( x + 1 )}{2})
