If the angle is (-90^\circ), where will the terminal side lie?यदि कोण (-90^\circ) है तो अंतिम भुजा कहाँ होगी?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: On negative (y)-axisऋणात्मक (y)-अक्ष पर
(-90^\circ) is clockwise rotation so the terminal side lies on the negative (y)-axis. The negative sign shows direction.(-90^\circ) दक्षिणावर्त घूर्णन है इसलिए अंतिम भुजा ऋणात्मक (y)-अक्ष पर होती है। ऋणात्मक चिन्ह दिशा बताता है।
