Differentiating Trig Functions
How do I differentiate trig functions?
- For calculus with trigonometric functions, angles must be measured in radians
- The derivative of is
- The derivative of is
- The derivative of is
- The following two sets of relationships can be derived using the chain rule, but are useful to know!
- For the linear function, where and are constants,
- the derivative of is
- the derivative of is
- the derivative of is
- For the general function ,
- the derivative of is
- the derivative of is
- the derivative of is
Examiner Tip
- Remember that these rules only work in radians!
Worked example
Gradient of tangent is equal to gradient of curve. To find the gradient, differentiate...
