Trigonometry is one of the major parts of Mathematics which deals with functions of angles and how they are calculated and used for other measurements. Trigonometry is introduced to students in CBSE class 10. Students are always advised to be fluent and should be thorough with these questions as they are very important from the exam point of view. Trigonometry has a weightage of 12 marks in the 10th board exam.
The six functions of trigonometry are:
Trigonometry plays the most vital role in almost all the fields whether its aviation, physics, criminology, military, marine biology, development of sound waves, satellite navigation, medical imaging, etc.
To find the angles or the sides of the right-angled triangle, trigonometry is used.
The trigonometric formulas are based on the three sides of a right-angled triangle, having hypotenuse (the longest side), base (adjacent side), height (opposite side), and angle θ.
If we apply the Pythagoras theorem for the right-angled triangle, we have:
(Perpendicular)2 + (Base)2 = (Hypotenuse)2 ⇒ (P)2 + (B)2 = (H)2
