Solving Trigonometry Problems Using The Sine Rule - By Enda King
How to use this applet:This is a very simple applet to use. To start click on the Start button and enter the length of the base and the size of the two angles. Ten to go through each of the steps click the Next button. When you reach the end click the Reset button to start all over again.Notes on the maths used in the applet:This applet uses the Sine rule to solve a simple trigonometric problem. The Sine rule is defined as (a / Sin A) = (b / Sin B) = (c / Sin C).
The base of the triangle is entered by the user and is taken as b. Angle B is also entered along with Angle A. The length of side a = (Sin A * (b / Sin B)).
To calculate the length of side c we need Angle C. This is calculated by adding angles A and B and subtrating them from 180(The number of degrees in a triangle).
The length of side c = (Sin C * (b / Sin B)).
The three lengths of hte triangle are now calculated. Other useful information: If you do not enter any value for the base or one of the angle the triangle will only be half constructed or not at all so enter the relevent values!
