So let us start with the concept which we are going to use here for this question.
00:07
So using point and slope form, the equation of tangent is given by y minus of y1 is equals to the slope m times of the x minus x1.
00:20
So we need to find this coordinates y1, x1 and slope m, so that we can find a tangent equation.
00:28
So we are given an equation that is which represent the equation of circle basically, x plus 2 whole square plus y minus 3 whole square is equals to the 37.
00:41
Let's say this as equation number first, while its corresponding diagram is also given to us in the graph.
00:49
So if you see from the graph, we are given a point, let's say the point p whose coordinates are given 4, 2.
01:00
So here the center of the circle would be equals to how much? that is minus of 2, 3.
01:08
How did it comes from this equation? that is this is minus of 2 and minus of 3.
01:14
This will represent the center of the circle.
01:18
Now similarly, if we try to find the radius of the circle, so this 37 representing the radius here, so that will be r is equals to under root of 37...
