Write All The Other Trigonometric Ratios Of Angle A In Terms Of 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.

Write All The Other Trigonometric Ratios Of Angle A In Terms Of 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. 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. Trigonometric ratios identities. several trigonometric ratios identities make our calculations simpler such as: sin 2 θ cos 2 θ = 1; 1 tan 2 θ = sec 2 θ; 1 cot 2 θ = cosec 2 θ; there are also some variations of the above 3 identities, which are nothing but rearranging the ones given above. trigonometric ratios of complementary. Find the sine ratio of θ in standard position whose terminal arm passes through (3, 4) if tanθ = 2, find the values of other trigonometric ratios. ∠acd is an exterior angle of Δ abc.

Find the sine ratio of θ in standard position whose terminal arm passes through (3, 4) if tanθ = 2, find the values of other trigonometric ratios. ∠acd is an exterior angle of Δ abc. To do: we have to write all the other trigonometric ratios of ∠a ∠ a in terms of sec a s e c a. solution: we know that, sin2 a cos2 a = 1 s i n 2 a c o s 2 a = 1. therefore, sin2 a = 1 − cos2 a sin 2 a = 1 − cos 2 a. = 1 − 1 sec2 a = 1 − 1 sec 2 a. = sec2 a−1 sec2 a = sec 2 a − 1 sec 2 a. The trigonometric ratios sin a, sec a, and tan a can be expressed in terms of cot a as 1 √(1 cot 2 a), √(1 cot 2 a) cot a and 1 cot a respectively. ☛ related questions: write all the other trigonometric ratios of ∠a in terms of sec a.
