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

Ex 8 3 2 Write All Trigonometric Ratios 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 = √. 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.

Write All The Other Trigonometric Ratios Of Angle A In Terms Of Sec Express the following in term of angles between 0°and 45°: sin 59° tan 63° express the following in term of angles between 0°and 45°: cosec 68° cot 72° express the following in term of angles between 0°and 45°: cos 74° sec 67° evaluate: 3 cos 80° cosec 10° 2 sin 59° sec 31°. evaluate: `(sin 80°) (cos 10°)` sin 59° sec 31°. Write all the other trigonometric ratios of angle a in terms of sec aq: write all the other trigonometric ratios of ∠ a in terms of sec a.hint 💡 cosec a = 1 cbse exam, class 10. Express the trigonometric ratios sin a, sec a and tan a in terms of cot a. 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.
