What values between 0 ∘ and 360 ∘ may A have when sin A = 1 2 ?

Given that sin A = 1 2 ⇒ sin A = sin 45 ∘ or sin 180 ∘ - 45 ∘ ⇒ sin A = sin 45 ∘ or sin 135 ∘ ⇒ A = 45 ∘ or 135 ∘

What values between 0 ∘ and 360 ∘ may A have when cos A = - 1 2 ?

Given that cos A = - 1 2 ⇒ cos A = - cos 60 ∘ ⇒ cos A = cos 180 ∘ - 60 ∘ or cos 180 ∘ + 60 ∘ ⇒ cos A = cos 120 ∘ or cos 240 ∘ ⇒ A = 120 ∘ or 240 ∘

What values between 0 ∘ and 360 ∘ may A have when tan A = - 1 ?

Given that tan A = - 1 ⇒ tan A = - tan 45 ∘ ⇒ tan A = tan 180 ∘ - 45 ∘ or tan 360 ∘ - 45 ∘ ⇒ tan A = tan 135 ∘ or tan 315 ∘ ⇒ A = 135 ∘ or 315 ∘

What values between 0 ∘ and 360 ∘ may A have when cot A = - 3 ?

Given that cot A = - 3 ⇒ cot A = - cot 30 ∘ ⇒ cot A = cot 180 ∘ - 30 ∘ or cot 360 ∘ - 30 ∘ ⇒ cot A = cot 150 ∘ or cot 330 ∘ ⇒ A = 150 ∘ or 330 ∘

What values between 0 ∘ and 360 ∘ may A have when sec A = - 2 3 ?

Given that sec A = - 2 3 ⇒ sec A = - sec 30 ∘ ⇒ sec A = sec 180 ∘ - 30 ∘ or sec 180 ∘ + 30 ∘ ⇒ sec A = sec 150 ∘ or sec 210 ∘ ⇒ A = 150 ∘ or 210 ∘
