Question

Find the equation of tangent to the circle x2 +y2 -3x+2y=0 at the origine​

Answer 1

Step-by-step explanation:

-1x+4y because 2x-3x is -1x

and 2y+2y is +4y

Answer 2

• The radius of the circle is v3.

• The two points are: +v2:1, -v2:1.

• If z is the angle of one of the tangents, then sin(z) = v2/v3 = v3/y,

• where y is the ordinate of one of the tangents.

• This tangent, therefore is the st line connecting the points (3/v2,0) and (v2,1).

• The other tangent is the line connecting the points (-3/v2,0) and (-v2,1).
