Question

5. Find the equation of the tangent to 9x2 + 16y2 = 144
which makes equal intercepts on the co-ordinate axes.​

Answer 1

Answer:

⇒16x2+9y2=1.

4xcosθ+3ysinθ=1.

⇒cosθ4x+sinθ3y=1.

∵cosθ4=sinθ3 (tangent makes equal intercepts with coordinates axes)

⇒tanθ=43.

=37o∴cosθ=54,sinθ=53.

of tangent ⇒4x×54+3y×53=1.
