hi, I am stuck on this question for homework : I'm not sure how to find the answer, as I thought integration is used only if the curve intersects at the x axis ? Thanx for any help 1.) The equation of circle x^-8x+y^2-10y=-16 It intersects the y axis at two points : (0,2) and (0,8) Find the small area between the curve and the y axis.(on the left of the y axis) 2.) Also, the chord between 0,2 and 0,8 on the circle subtends an angle at the centre (4,5). Show that the angle is 7/25 using the cosine rule. I'm not sure what to do here as well..
