Intercambiar lados

cot (2 x + 5) = tan (2 5^{\circ})

Aplicar propiedades trigonométricas inversas

cot (2 x + 5) = tan (2 5^{\circ})

Soluciones generales para

cot (2 x + 5) = tan (2 5^{\circ})

cot (x) = a \Rightarrow x = arccot (a) + 18 0^{\circ} n

2 x + 5 = arccot (tan (2 5^{\circ})) + 18 0^{\circ} n

2 x + 5 = arccot (tan (2 5^{\circ})) + 18 0^{\circ} n

Resolver

2 x + 5 = arccot (tan (2 5^{\circ})) + 18 0^{\circ} n : x = - \frac{5}{2} + 32. 5^{\circ} + \frac{18 0 ^{\circ} n}{2}

2 x + 5 = arccot (tan (2 5^{\circ})) + 18 0^{\circ} n

Simplificar

arccot (tan (2 5^{\circ})) + 18 0^{\circ} n : 6 5^{\circ} + 18 0^{\circ} n

arccot (tan (2 5^{\circ})) + 18 0^{\circ} n

arccot (tan (2 5^{\circ})) = 6 5^{\circ}

arccot (tan (2 5^{\circ}))

Re-escribir usando identidades trigonométricas:

tan (2 5^{\circ}) = cot (6 5^{\circ})

tan (2 5^{\circ})

cot (9 0^{\circ} - x) = tan (x)

= cot (9 0^{\circ} - 2 5^{\circ})

= cot (6 5^{\circ})

= arccot (cot (6 5^{\circ}))

Use the inverse trig property:

6 5^{\circ}

arccot (cot (6 5^{\circ}))

Para

0 < x < 18 0^{\circ}

,

a rcco t (co t (x)) = x

0 < 6 5^{\circ} < 18 0^{\circ}

= 6 5^{\circ}

= 6 5^{\circ}

= 6 5^{\circ} + 18 0^{\circ} n

2 x + 5 = 6 5^{\circ} + 18 0^{\circ} n
