Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFमाना परवलय का ध्रुव y2 = 4ax, p(n, k) है
सामान्य जीवा का समीकरण निम्न है;
y = -tx + 2at + at3
y + tx – 2at – at3 = 0 …1)
P के सन्दर्भ में ध्रुवीय का समीकरण T = 0 है
ky = 2a (x + n)
2ax – ky + 2an = 0 …2)
अब समीकरण 1) और समीकरण 2) एक ही रेखा के समीकरण को निरूपित करते हैं
तो, दोनों समीकरणों की तुलना करने पर;
साथ ही,
t को 3 से प्रतिस्थापित करने पर
k2 (n + 2a) + 4a3 = 0
समीकरण का सामान्यीकरण करने पर, हम प्राप्त करते हैं;
y2 (x + 2a) + 4a3 = 0
