Question

if tan theta + sin theta is equal to p, 10 theta minus sin theta is equal to q prove that p square minus q square is equal to 4 root PQ

Answer 1

Answer:

Step-by-step explanation:

tanФ+sinФ=p

tanФ-sinФ=q

prove that:

p²-q²=4√pq

solution:

(tanФ+sinФ)²-(tanФ-sinФ)²=4√pq

⇒(tan²Ф+sin²Ф+2tanФsinФ)-(tan²Ф+sin²Ф-2tanФsinФ)

⇒1+2tanФsinФ-1+2tanФsinФ

⇒4tanФsinФ

iske agae  tum khud solve kar lena

mujhe nahin araha hai abhi
