2 Write All The Other Trigonometric Ratios Of A In Terms Of Sec A

2 Write All The Other Trigonometric Ratios Of A In Terms Of Sec A Transcript. ex 8.3, 2 write all the other trigonometric ratios of ∠ a in terms of sec a. cos a we know that cos a = 𝟏 𝒔𝒆𝒄⁡𝑨 tan a we know that 1 tan2 a = sec2 a tan2 a = sec2 a − 1 tan a = ± √ (𝑠𝑒𝑐2 𝐴 −1) here, a is acute angle (i.e. less than 90°) & tan a is positive when a is acute ∴ tan a = √. Q. write all the other trigonometric ratios of a in terms of seca. q. question 2. write all the other trigonometric ratios of ∠ a in terms of sec a. q. write all the other trigonometric ratios of ∠a in terms of sec a. q. express the trigonometric ratios sina seca and tana in terms of cot a.

Ex 8 3 2 Write All Trigonometric Ratios In Terms Of Sec A Click here:point up 2:to get an answer to your question :writing hand:write all the other trigonometric ratios of a in terms of seca. Write all the other trigonometric ratios of ∠a in terms of sec a. solution: we will use the basic trigonometric identities and properties of the trigonometric ratios to solve the problem. sin 2 a cos 2 a = 1. cosec 2 a = 1 cot 2 a. sec 2 a = 1 tan 2 a. we know that, cos a = 1 sec a equation (1) also, sin 2 a cos 2 a = 1. Question 2. write all the other trigonometric ratios of ∠a in terms of sec a. solution: (i) cos a. cos a = 1 sec a (ii) sin a. we know that. sin 2 a = 1 – cos 2 a. also , cos 2 a = 1 sec 2 a. sin 2 a = 1 – 1 sec 2 a. sin 2 a = (sec 2 a – 1) sec 2 a. sin a = (sec 2 a – 1) 1 2 sec a (iii) tan a. we know that. tan 2 a 1 = sec 2. 2. write all the other trigonometric ratios of a in terms of sec afor short notes, revision notes and ncert solution.visit us at kwatratuitioncenter.
