How to get the values of a and b? i need to differentiate first the equation?

Step-by-step explanation:

We are given the equation of the curve:

(1)

And the equation of the line that is normal (perpendicular to that curve) in the point :

(2)

Note this equation has the form , where is the slope of the line that es normal to the curve and the intersection of that line with the y-axis.

Well, let’s begin by finding the slope of the line that is tangent to the curve by differentiating the equation (1):

(3)

Then, we have to evaluate that when (remember we are given the point ):

(4) This is the slope of the line that is tangent to the curve

And the slope of the line that is perpendicular to that tangent line is its negative reciprocal. Hence:

(5) This is the slope of the line normal to the curve

Then:  

(6)

Rewritting (2):

(7)

Evaluating in the point :

(8)

Finding :

(9) This is the value of

Substituting (9) in (6):

(10)

(11) This is the value of

you should at least use a calculater

step-by-step explanation:

definition: a circle is the  set of all points in a plane that are equidistant  from a given  point  called the center of the circle. we use the symbol ⊙ to represent a circle. the a line segment from the center of the circle to  any point  on the circle is a radius of the circle.

i googled it and this is what i got i don't know how it is. sorry.
