Sinus e ark sinus, e degre

Ngam trigonometri, adoro ƴeewde ɓetirgal lobbudu ngal: D tokooso e yaynirde ndee firti ko degre. Ñoƴƴu sinus, tappu 30, uddu parantees, e foti. sin⁡30∘\displaystyle \sin 30^{\circ} ko 12\displaystyle \dfrac{1}{2}, no feccere. Ñoƴƴu S D ngam limre toɓɓere: 0.5. sin⁡−1\displaystyle \sin^{-1} ko binndol oolol dow butoŋ sin. Ñoƴƴu shift e sinus, tappu 0.5, uddu parantees, e foti; jaabawol ko degre 30.
