From the formula, we already know that tan (arctan x) = x

tan y = x

Now on differentiating both sides and using the chain rule we get,

sec²y dy/dx = 1

dy/dx = 1 / sec²y

According to the trigonometric identity we have sec²y = 1 + tan²y

dy/dx = 1 / (1 + tan²y)

On substitution,

Thus, d(arctan x) / dx = 1 / (1 + x²
