The application of trigonometry is done in astronomical studies and other science fields. For example if you are on the terrace of a tall building of known height and you see a post box on the other side of the road. There are many interesting applications of Trigonometry that one can try out in their day-to-day lives.
The area of a triangle in terms of its semi-perimeter and side lengths can be written as. All the formulas of trigonometry chapter are provided here for students to help them solve problems quickly. All these trigonometric ratios are defined using the sides of the right triangle such as an adjacent side opposite side and hypotenuse side.
