- Derivative of tan (x): sec² (x)
- Derivative of cot (x): csc² (x)
- Derivative of sec (x): sec (x) tan (x)
- Derivative of csc (x): csc (x) cot (x)
These derivatives form the groundwork for separate more complex trigonometric expressions.
Derivative of Cosx Sinx
To observe the derivative of Derivative Cosx Sinx, we require to apply the product rule. The production rule states that if you have two functions, u (x) and v (x), the derivative of their product is yield by:
d dx [u (x) v (x)] u (x) v (x) u (x) v (x)
In our case, let u (x) cos (x) and v (x) sin (x). Then, u (x) sin (x) and v (x) cos (x). Applying the product rule, we get:
d dx [cos (x) sin (x)] (sin (x)) sin (x) cos (x) cos (x)
