M= Slope fla JJDJame Jacob Calculus I: The Circle A) The equation xty = 1 is a unit circle centered at the origin. 1) what is the slope of the line tangent to the curve at the point ( 0, 1) on this curve? ") what is the equation of this line? 3) What is the slope of the tangent at ( 1,0)? 4) What is the equation of the tangent? 5) what is the slope of the tangent at any Point ( Xo, yo ) on this curve? 6) What is the equation of this line? 3) IT is defined as the # of diameters needed to go around the circumference of a circle Thus: C= FTD. From this definition construct an argument on back to explain why the Area of a Circle ( A) is given by the Formula A = Fir 2 where is the radius of the circle
