Differentiating sine

Differentiate sine functions, including constant multiples and linear angles.

  • With angles in radians, .
  • A constant multiplier stays in front: .
  • For a linear angle, .
  • Keep the inner angle and multiply by its derivative . An added constant has derivative .

Example 1

Differentiate with respect to . Angles are in radians.

Differentiate the inner expression.Sine differentiates to cosine. Multiply by the constant and the inner derivative.

Example 2

Differentiate with respect to . Angles are in radians.

Differentiate the inner expression.Sine differentiates to cosine. Multiply by the constant and the inner derivative.

Remember
Check the inner derivative before simplifying your answer.
