Question

Find the acute angle between the pair of
lines represented by the following equations.
(1) x2 - 7xy + 12y2 = 0
(ii) y2 - xy - 6x2 = 0
(iii) (xcosa – ysina)² = (x² + y²) sin’a
(iv) x² + 2xy cota - y² = 0.
​

Answer 1

Answer:

equations.

(1) x2 - 7xy + 12y2 = 0

(ii) y2 - xy - 6x2 = 0

(iii) ( = (x²

(iv) x² + 2xy cota - y² = 0.
