Sin 270 A. In this video we will learn how the values of different trigonometric ratios change based on their angle or in different quadrants.
TRIGONOMETRIC RATIOS OF 270 DEGREE PLUS THETA Trigonometric ratios of 270 degree plus theta is one of the branches of ASTC formula in trigonometry Trigonometricratios of 270 degree plus theta are given below sin (270° + θ) = cos θ cos (270° + θ) = sin θ tan (270° + θ) = cot θ csc (270° + θ) = sec θ sec (270° + θ) = cos θ.

Answer (2) 0 Solution We know that sin (270° + x) = cos x sin (270° – x) cos x cos (180° + x) = cos x cos A + sin (270° + A) – sin (270° – A) + cos (180° + A) cos A – cos A – ( cos A) + ( cos A) = cos A – cos A + cos A – cos A.
Answer (1 of 5) sin (270° θ) = sin [180° + 90° θ] = sin [180° + (90° θ)] = sin (90° θ) [since sin (180° + θ) = sin θ] Therefore sin (270° θ) = cos θ [since sin (90° θ) = cos θ] Let see how we get sin (90° θ) = cos θ and sin(180° + θ) = sin θ From the above image it.
