Example Calculations

Below are some examples of how the calculator works.

Example 1: Derivative of sin(x)

Input

Function: sin(x)

Output

Derivative: cos(x)

Explanation

The derivative rule states:

d/dx [sin(x)] = cos(x)

This means the rate of change of sin(x) at any point is represented by cos(x).

Example 2: Derivative of cos(x)

Input

Function: cos(x)

Output

Derivative: -sin(x)

Explanation

The derivative of cosine is negative sine.

d/dx [cos(x)] = -sin(x)

This is one of the most commonly used derivative formulas in calculus.

Example 3: Derivative of tan(x)

Input

Function: tan(x)

Output

Derivative: sec²(x)

Explanation

The derivative of tangent is the square of secant.

d/dx [tan(x)] = sec²(x)

This formula appears frequently in optimization and related rates problems.

Example 4: Derivative of sec(x)

Input

Function: sec(x)

Output

Derivative: sec(x)tan(x)

Explanation

The derivative involves both secant and tangent functions.

d/dx [sec(x)] = sec(x)tan(x)

Understanding Trigonometric Derivatives
