Explanation Let the acute angle be 35 ° and 55 ° for triangle 1; 20 ° and 70 ° for triangle 2; 85 ° and 5 ° for triangle 3 Given that, the angles of the right triangle 1 are 35 ° and 55 ° . The graph of the triangle 1 is shown below in the Figure 1. The sine of the first angle is calculated as follows. sin 35 ° = 0.5736 The cosine of the second angle is calculated as follows. cos 55 ° = 0.5736 . Given that, the angles of the right triangle 2 are 20 ° and 70 ° . The graph of the triangle 2 is shown in Figure 2. The sine of the first angle is calculated as follows. sin 20 ° = 0.3420 The cosine of the second angle is calculated as follows. cos 70 ° = 0.3420 . Given that, the angles of the right triangle 3 are 85 ° and 5 ° . The graph of the triangle 3 is shown in Figure 3. The sine of the first angle is calculated as follows. sin 85 ° = 0.9962 The cosine of the second angle is calculated as follows. cos 5 ° = 0.9962 . The table below represents the sine and cosine values of each triangle, that has been computed above

Family of Curves

A family of curves is a group of curves that are each described by a parametrization in which one or more variables are parameters. In general, the parameters have more complexity on the assembly of the curve than an ordinary linear transformation. These…

XZ Plane

In order to understand XZ plane, it's helpful to understand two-dimensional and three-dimensional spaces. To plot a point on a plane, two numbers are needed, and these two numbers in the plane can be represented as an ordered pair (a,b) where a and b are…

Euclidean Geometry

Geometry is the branch of mathematics that deals with flat surfaces like lines, angles, points, two-dimensional figures, etc. In Euclidean geometry, one studies the geometrical shapes that rely on different theorems and axioms. This (pure mathematics) ge…

Lines and Angles

In a two-dimensional plane, a line is simply a figure that joins two points. Usually, lines are used for presenting objects that are straight in shape and have minimal depth or width.
