Angulo Doble. Reducir​

Answer 1

Respuesta:

R = 4 + sec³(x)

Explicación paso a paso:

R = (sen(2x) / cos(x))² + (sen(2x) / sen(x))² + (sen(x) / sen(x)cos(x))³

R = (2sen(x)cos(x) / cos(x))² + (2sen(x)cos(x) / sen(x))² + (1 / cos(x))³

R = (2sen(x))² + (2cos(x))² + (sec(x))³

R = 4sen²(x) + 4cos²(x) + sec³(x)

R = 4(sen²(x) + cos²(x)) + sec³(x)

R = 4(1) + sec³(x)

R = 4 + sec³(x)

R = 4 + sec²(x)*sec(x)

R = 4 + (1 + tg²(x))sec(x)

R = 4 + sec(x) + tg²(x)sec(x)
