[QUOTE="sarthak sharma, post: 4990819, member: 528746"] [h2]Homework Statement [/h2] if the tangent at a point P("theta") on the ellipse [INDENT][INDENT][INDENT][INDENT][INDENT][INDENT][INDENT][INDENT][INDENT]16 (x^2) + 11 (y^2) = 256[/INDENT][/INDENT][/INDENT][/INDENT][/INDENT][/INDENT][/INDENT][/INDENT][/INDENT] is also tangent to the circle [INDENT][INDENT][INDENT][INDENT][INDENT](x^2) + (y^2) + 2(x) = 15[/INDENT][/INDENT][/INDENT][/INDENT][/INDENT] then ("theta") = ?? [B]2. The attempt at a solution[/B] [INDENT][INDENT][INDENT][INDENT][INDENT][INDENT][INDENT][INDENT]{{{{ i have taken "theta" as "d" }}}}[/INDENT][/INDENT][/INDENT][/INDENT][/INDENT][/INDENT][/INDENT][/INDENT] P [4 cos d , (16/(sqrt11)) sin d] equation of tangent at P on ellipse is {(cos d) / 4] x + [(sin d) / (16/(sqrt11))] y = 1 .....(i) centre of given circle C(-1,0) and radius r = 4 for (i) to also be tangent on the circle - perpendicular distance of (i) from C must be equal to 4 but when i tried to do so i could not get the answer may be I am doing something wrong so please anyone could guide me the correct way [/QUOTE]
