Maths4all Express Trigonometry Ratios In Terms Of Cot Sec Cosec Transcript. ex 8.3, 1 express the trigonometric ratios sin a, sec a and tan a in terms of cot a. tan a we know that tan a = 𝟏 𝒄𝒐𝒕𝑨 cosec a we know that 1 cot2 a = cosec2 a cosec2 a = 1 cot2 a cosec a = ± √ (1 𝑐𝑜𝑡2 𝐴) here, a is acute angle (i.e. less than 90°) & cosec a is positive when a is acute ∴ cosec. Question 1. express the trigonometric ratios sin a, sec a, and tan a in terms of cot asolution: (i) sin awe know thatcosec2a = 1 cot2a1 sin2a = 1 cot2asin2a = 1 (1 cot2a)sin a = 1 (1 cot2a)1 2(ii) sec a sec2a = 1 tan2asec2a = 1 1 cot2asec2a = (cot2a 1) cot2asec a = (cot2a 1)1 2 cot a(iii) tan atan a = 1 cot atan a = cot 1 a que.
Maths4all Express Trigonometry Ratios In Terms Of Cot Sec Cosec 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. Express the trigonometric ratios sin a, sec a and tan a in terms of cot a. solution: we will use the basic trigonometric identities and properties of the trigonometric ratios to solve the problem. consider a Δabc with ∠b = 90° using the trigonometric identity, cosec 2 a = 1 cot 2 a (by taking reciprocal both the sides) 1 cosec 2 a = 1 (1.

Trigonometric ratios (definition, formulas, examples). Since we know that cosecant is the reciprocal of sine, secant is the reciprocal of sine, and cotangent is the reciprocal of tangent, we can construct these functions as follows: sec a = 1 cos a = 25 24 csc a = 1 sin a = 25 7 cot a = 1 tan a = 24 7 sec. . a = 1 cos a = 25 24 csc. . a = 1 sin a = 25 7 cot. .
