Cosine is used because we know T 3. Hence, cosϴ = T3X / T3 (entire tension); T3X = T3 x cosϴ. Therefore, a0= (T1-T2+T3 cosϴ) / m. From this we finally find the tension at an angle formula, T1= ma0 – T2 + T3 cosϴ. tension at an angle. on mars fueled opensource software

WebbA 'small angle' is equally small whatever system you use to measure it. Thus if an angle is, say, much smaller than 0.1 rad, it will be much smaller than the equivalent in degrees. More typically, saying 'small angle approximation' typically means $\theta\ll1$, where $\theta$ is in radians; this can be rephrased in degrees as $\theta\ll 57^\circ$.
