WebJul 31, 2016 · Explanation: The solution: arctanx is an angle whose tangent function = x 1. Considering the sides of the right triangle. We have opposite side = x, adjacent side = 1 and hypotenuse = √x2 + 1. Therefore the sine of this angle = opposite side hypotenuse = x √x2 + 1. God bless....I hope the explanation is useful. WebDraw a right triangle and label one of the angles θ. If θ = arctan ( x / 5) then the (non-hypotenuse) side opposite θ can be x, and the side adjacent θ will be 5. The hypotenuse is x 2 + 25 by the Pythagorean theorem. Now, sec θ = 1 / cos θ, which is the hypotenuse divided by the adjacent side: sec ( arctan ( x / 5)) = x 2 + 25 5.
