    The tangent of what angle is zero? The sine of what angle is zero?

    arctan(0) = arcsin(0)/arccos(0) so you just have inverse functions. So the sinx = 0 if x = 0 and cosx = 0 if x = Pi/2 so in this case your answer is 0

    That's what I was trying to define for you. Have you meat the tangent function? It is NOT the case that \(atan(x) = \dfrac{asin(x)}{acos(x)}\). That is just incorrect. It is not the case that tan(x) = 0 where cos(x) = 0. That is just incorrect.

    \(tan^{-1}(x) = arctan(x) = atan(x)\) It is the invere of the Tangent function. If \(\tan(\theta) = b\;then\;\theta = atan(b)\;for\;-\dfrac{\pi}{2} < \theta < \dfrac{\pi}{2}\)
