Sum of Angles of a Quadrilateral
Sum of angles of a quadrilateral are discussed here. We have now two triangles in the below figure.
We know, the sum of the angles of a triangle = 180°
Since there are two triangles,
therefore, the sum of two triangles is 180° + 180° = 360°
Note: The sum of the four angles is 360°.... |

# Prove that the curves xy = 4
Question:
Prove that the curves xy = 4 and x2 + y2 = 8 touch each other.
Solution:
Given curves are equations of two circles,
xy = 4 ….. (i) and
x2 + y2 = 8 …. (ii)
Different equation (i) w.r.t., x
$x \cdot \frac{d y}{d x}+y \cdot 1=0$
$\Rightarrow \frac{d y}{d x}=-\frac{y}{x} \R... |
# Arc Length and Surface Area
In this section, we'll study a few more geometric objects using the definite integral. First, we'll ask how to determine the distance we've travelled if we drive along a curvy graph. Then we'll tackle roughly the same question for surfaces of revolution by computing the surface area.
