In Problems 27 through 31, a function y = g(x) is described by some geometric property of its graph. Write a differential equation of the form dy/dx = f(x, y) having the function g as its solution (or as one of its solutions). 27. The slope of the graph of g at the point (x, y) is the sum of x and y. 28. The line tangent to the graph of g at the point (x, y) inter- sects the x-axis at the point (x/2,0). 29. Every straight line normal to the graph of g passes through the point (0, 1). Can you guess what the graph of such a function g might look like? -30. The graph of g is normal to every curve of the form y = x2 + k (k is a constant) where they meet. 31. The line tangent to the graph of g at (x, y) passes through the point (-Y. r) %3D
Angles in Circles
Angles within a circle are feasible to create with the help of different properties of the circle such as radii, tangents, and chords. The radius is the distance from the center of the circle to the circumference of the circle. A tangent is a line made perpendicular to the radius through its endpoint placed on the circle as well as the line drawn at right angles to a tangent across the point of contact when the circle passes through the center of the circle. The chord is a line segment with its endpoints on the circle. A secant line or secant is the infinite extension of the chord.
Arcs in Circles
A circular arc is the arc of a circle formed by two distinct points. It is a section or segment of the circumference of a circle. A straight line passing through the center connecting the two distinct ends of the arc is termed a semi-circular arc.
