2016-12-20 · From Euler’s formula for e ix you can immediately obtain the formulas for cos 2A and sin 2A without going through the formulas for sums of angles. Here’s how. Remember the laws of exponents: x ab = (x a) b. One important special case is that x 2b = (x b)². Use that with Euler’s formula: cos 2A + i sin 2A = e i(2A) cos 2A + i sin 2A = (e

The arctangent of x is defined as the inverse tangent function of x when x is real (x ∈ℝ). When the tangent of y is equal to x: tan y = x. Then the arctangent of x is equal to the inverse tangent function of x, which is equal to y: arctan x = tan-1 x = y.
