While we can find the value for arctangent for any x value in the interval [-∞, ∞], there are certain angles that are used frequently in trigonometry (0°, 30°, 45°, 60°, 90°, and their multiples and radian equivalents) whose tangent and arctangent values may be worth memorizing.What is the relation among all the trigonometrical ratios of (90° - θ)? In trigonometrical ratios of angles (90° - θ) we will find the relation between all six trigonometrical ratios. (tan-1 or atan) of a number, it cannot return an infinitely long list of angles, so by convention, it finds just the first one. We should learn it like cos 0° = sin 90° = 1 cos 30° = sin 60° = √3/2 We would like to show you a description here but the site won't allow us. cot 2 θ + 1 = csc 2 θ. Trigonometry Questions. cot ( 90° + θ) = - tan θ. Following is the URL of video explaining the derivation identity sin (90 - x) https: Tan 90° = Sin 90 0 / Cos90° From the trigonometric table, we know, Sin 90° = 1 And, Cos 90° = 0 ∴ Tan 90°= 1/0 = Undefined That means, we cannot define Tan 90 0 value.
