tan^2(45-x/3)=0.58

الحلّ

tan^{2} (4 5^{\circ} - \frac{x}{3}) = 0.58

الحلّ

x = - 54 0^{\circ} n + 13 5^{\circ} - 3 \cdot 0.65086 \dots, x = - 54 0^{\circ} n + 13 5^{\circ} + 3 \cdot 0.65086 \dots

راديان

x = \frac{3 π}{4} - 3 \cdot 0.65086 \dots - 3 πn, x = \frac{3 π}{4} + 3 \cdot 0.65086 \dots - 3 πn

خطوات الحلّ

tan^{2} (4 5^{\circ} - \frac{x}{3}) = 0.58

بالاستعانة بطريقة التعويض

tan^{2} (4 5^{\circ} - \frac{x}{3}) = 0.58

tan (4 5^{\circ} - \frac{x}{3}) = u :

على افتراض أنّ

u^{2} = 0.58

u^{2} = 0.58 : u = 0.58, u = - 0.58

u^{2} = 0.58

x = f (a), - f (a)

الحلول هي

x^{2} = f (a)

لـ

u = 0.58, u = - 0.58

u = tan (4 5^{\circ} - \frac{x}{3})

استبدل مجددًا

tan (4 5^{\circ} - \frac{x}{3}) = 0.58, tan (4 5^{\circ} - \frac{x}{3}) = - 0.58

tan (4 5^{\circ} - \frac{x}{3}) = 0.58, tan (4 5^{\circ} - \frac{x}{3}) = - 0.58

tan (4 5^{\circ} - \frac{x}{3}) = 0.58 : x = - 54 0^{\circ} n + 13 5^{\circ} - 3 arctan (0.58)

tan (4 5^{\circ} - \frac{x}{3}) = 0.58

Apply trig inverse properties

tan (4 5^{\circ} - \frac{x}{3}) = 0.58

tan (4 5^{\circ} - \frac{x}{3}) = 0.58 :

حلول عامّة لـ

tan (x) = a \Rightarrow x = arctan (a) + 18 0^{\circ} n

4 5^{\circ} - \frac{x}{3} = arctan (0.58) + 18 0^{\circ} n

4 5^{\circ} - \frac{x}{3} = arctan (0.58) + 18 0^{\circ} n

4 5^{\circ} - \frac{x}{3} = arctan (0.58) + 18 0^{\circ} n

حلّ:

x = - 54 0^{\circ} n + 13 5^{\circ} - 3 arctan (0.58)
