Thanks. algebra-precalculus trigonometry Share Cite Follow edited Jun 12, … WebThis can be rewritten as 1+ cosθ sinθ 2 = 1 sinθ 2 that is as 1+cot 2θ = cosec θ Again, we see one of our new trigonometric functions, cosecθ, appearing in an identity. Example Suppose we wish to solve the trigonometrical equation cot2 θ = 3 for 0 ≤ θ < 360 We begin the solution by taking the square root: cotθ = √ 3 or − √ 3 It ...

WebThus, we can say that the domain of tan-1 x is all real numbers and the range is (-π/2, π/2). An interesting fact to note is that we can extend the arctan function to complex numbers. In such a case, the domain of arctan will be all complex numbers. Arctan Table.
