Along the same lines, using the aforementioned form, can you look up terms such as cos -270° value, cos -270, cos-270° value and what is the cos of -270 degrees, just to name a few. Given the periodic property of cosine of -270°, to determine the cosine of an angle -360°, e.g. -990°, calculate cos -990° as cos (-990 Mod 360)° = cosine of ...9) cos θ x y 270 ° 10) tan θ x y 225 ° 11) cos 270 ° 12) sin 0 13) cot 7π 4 14) csc 2π 3 15) csc 225 ° 16) sin 300 ° 17) csc 90 ° 18) tan 240 ° 19) sin π 4 20) tan 120 ° 21) tan − 13 π 6 22) cos −630 ° 23) cos 990 ° 24) csc − 31 π 6 25) csc − 5π 6 26) cos − 17 π 3 27) sin 29 π 6 28) sec 945 ° 29) cos − 11 π 2 Mar 16, 2018 · Answer is choice C The expression given is equivalent to -3i ===== Explanation: Using a calculator, a reference sheet, o… What are the relations among all the trigonometrical ratios of (270° - θ)? In trigonometrical ratios of angles (270° - θ) we will find the relation between all six trigonometrical ratios. We know that, sin (90° - θ) = cos θ. cos (90° - θ) = sin θ. tan (90° - θ) = cot θ. csc (90° - θ) = sec θ. sec (90° - θ) = csc θ. cot (90 ... In algebra, a quadratic equation (from Latin quadratus 'square') is any equation that can be rearranged in standard form as where x represents an unknown value, and a, b, and c represent known numbers, where a ≠ 0. (If a = 0 and b ≠ 0 then the equation is linear, not quadratic.) The numbers a, b, and c are the coefficients of the equation ...Yes, indeed: \cos(-2\pi) = \cos(2\pi) = 1. Formally, this is because \cos \theta is an even function, meaning \cos\theta = \cos(−\theta) for all \theta. This can be seen in a number of ways. ...Verified answer.
