Trigonometry Questions Trigonometry questions given here involve finding the missing sides of a triangle with the help of trigonometric ratios and proving trigonometry identities. We know that trigonometry is one of the most important chapters of Class 10 Maths. Hence, solving these questions will help you to improve your problem-solving skills. What is Trigonometry? The word ‘trigonometry’ is derived from the Greek words ‘tri’ (meaning three), ‘gon’ (meaning sides) and ‘metron’ (meaning measure). Trigonometry is the study of relationships between the sides and angles of a triangle. The basic sine of ∠A = sin A = Side opposite to ∠A/ Hypotenuse cosine of ∠A = cos A = Side adjacent to ∠A/ Hypotenuse tangent of ∠A = tan A = (Side opposite to ∠A)/ (Side adjacent to ∠A) cosecant of ∠A = cosec A = 1/sin A = Hypotenuse/ Side opposite to ∠A secant of ∠A = sec A = 1/cos A = Hypotenuse/ Side adjacent to ∠A cotangent of ∠A = cot A = 1/tan A = (Side adjacent to ∠A)/ (Side opposite to ∠A) Also, tan A = sin A/cos A cot A = cos A/sin A Also, read: Trigonometry Questions and Answers 1. From the given figure, find tan P – cot R. Solution: From the given, PQ = 12 cm PR = 13 cm In the right triangle PQR, Q is right angle. By Pythagoras theorem, PR 2 = PQ 2 + QR 2 QR 2 = (13) 2– (12) 2 = 169 – 144 = 25 QR = 5 cm tan P = QR/PQ = 5/12 cot R = QR/PQ = 5/12 So, tan P – cot R = (5/12) – (5/12) = 0 Trigonometric ratios of complementary angles: sin (90° ...

Important Questions for Class 10 Maths Chapter 8 Introduction to Trigonometry Introduction to Trigonometry Class 10 Important Questions Very Short Answer (1 Mark) Question 1. If tan θ + cot θ = 5, find the value of tan2θ + cotθ. (2012) Solution: tan θ + cot θ = 5 … [Given tan 2θ + cot 2θ + 2 tan θ cot θ = 25 … [Squaring both sides tan 2θ + cot 2θ + 2 = 25 ∴ tan 2θ + cot 2θ = 23 Question 2. If sec 2A = cosec (A – 27°) where 2A is an acute angle, find the measure of ∠A. (2012, 2017D) Solution: sec 2A = cosec (A – 27°) cosec(90° – 2A) = cosec(A – 27°) …[∵ sec θ = cosec (90° – θ) 90° – 2A = A – 27° 90° + 27° = 2A + A ⇒ 3A = 117° ∴ ∠A = \(\frac\) = 1.41, if required) (2014OD) Solution:
