If (\theta) is in the third quadrant, what are the signs of (\sin \theta) and (\cos \theta)?यदि (\theta) तृतीय चतुर्थांश में है, तो (\sin \theta) और (\cos \theta) के चिन्ह कैसे होंगे?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (\sin \theta) negative and (\cos \theta) negative(\sin \theta) ऋणात्मक और (\cos \theta) ऋणात्मक
In the third quadrant, both sine and cosine are negative. In exams use the ASTC rule to decide signs quickly.तृतीय चतुर्थांश में sine और cosine दोनों ऋणात्मक होते हैं। परीक्षा में ASTC नियम से signs जल्दी तय करें।
