Question

निम्न का मान क्या होगा ? *

​

Answer 1

Answer:

Cos²Θ + sin²Θ = 1

cos²Θ = 1 - sin²Θ

• 1 - sin²Θ का मान हैं - cos²Θ

More information :

›› sin²A + cos²A = 1

›› Sin² A = 1 - cos² A

›› 1 + tan² A = sec²A

›› 1 + cot²A = cosec² A

›› Tan A = sin A/cos A

›› Cot A = cos A/sin A

›› Sec A = 1/cos A

›› Cosec A = 1/Sin A
