We know that the differential of y(x) = x3 is 3x2. The process of reversing this, whereby we generate a function from its derivative is integration. i.e. = y(x) Integration of a differential gives the original function. and [ y(x).dx] = y(x) Differential of an integral gives the original function.

with θ = arctan(y/x) and r2 = x2 + y2. ... Then, assume that z changes by y changing alone. This would give us two expressions for the derivative of . f(z) = F(x,y). The first (holding y constant) can be written as. while the second (holding x constant) can be written as.

Now y = if and only if x = tan y. Hence taking the derivative of both sides of x = tan y, we get: 1 = ( = But ( y ( , sec y > 0 and hence = = . Therefore, = , ( x (. From the nature of the derivative of the arctan function we can observe that integrals of the form , where a > 0 can be evaluated by substituting x …

If y = sin x, then x = sin 1 y (also called arcsin y) y = cos x, then x = cos 1y (also called arccos y) y = tan x, then x = tan 1y (also called arctan y). Note: This is just an oddity of nomenclature: sin 1 y is . not. the same as (sin y) 1. Examples. 1. sin x = 0.32, x = sin 1 0.32 = 18.7 = 0.33 rads

Derivative of arctan(x) (Inverse tangent) | Detailed Lesson
And this is often very difficult or impossible to determine algebraically. Hence, the Theorem is only useful in general for evaluating the derivative of the inverse function on a point-by-point basis. Exercise 5a: Graph y = arctan(x) = , and numerically and graphically explore the value of the derivative a several points. Do you see a pattern?
