2*cos(2x) I would use the Chain Rule: First derive sin and then the argument 2x to get: cos(2x)*2 The chain rule in Calculus is used to differentiate a composite function such as follows $f (g (x))$ In the expression, $\sin (2x)$ there is a function inside of a function. The chain rule for derivatives is $\frac {dy} {dx} = \frac {dy} {du}\cdot \frac {du} {dx}$ Using the chain rule, the derivative of sin^2x is 2sin (x)cos (x) (Note – using the trigonometric identity 2cos (x)sin (x) = sin (2x), the derivative of sin^2x can also be written as sin (2x)) Finally, just a note on syntax and notation: sin^2x is sometimes written in the forms below (with the derivative as per the calculations above). How the Derivative Calculator Works. For those with a technical background, the following section explains how the Derivative Calculator works.

Find derivative of y=sin(2x)cos(3x) Involves chain rule and product rule with trig derivatives. Watch Now First 3 Derivatives of sin2x | Differentiation Walkthrough (Chain Rule) Complete list of worked integration and differentiation (calculus) problems: What is the Derivative of Sin(x)? we are going to share formula f derivative of sin (x) and proof . $$\frac{d}{dx} sin (x) = \lim_{d \to 0} \frac{(sin(x+d)- sin(x))}{d}$$ You may remember the following angle sum formula from high school: $$sin(a+b) = sin(a)cos(b) + sin(b)cos(a)$$ This lets us untangle the x […] what we want to do is find the derivative of this G of X and at first it could look intimidating we have a sine of X here we have a cosine of X we have this crazy expression here with a PI over cube root of x we're squaring the whole thing at first it might seem intimidating but as we'll see in this video we can actually do this with the tools already in our toolkit using our existing f′(x)=limh→0f(x+h)−f(x)h. Hence, (sin2x)′=limh→0sin2(x+h)−sin2(x)h=limh→ 0sin(2x+h)sin(h)h=limh→0sin(2x+h)⋅limh→0sinhh=(sin2x)⋅(1)=sin2x. We have only stated the rule here but it can easily be proved for all continuous, differentiable functions.

### Lesson 6-2

$$\frac{d}{dx} sin (x) = \lim_{d \to 0} \frac{(sin(x+d)- sin(x))}{d}$$ You may remember the following angle sum formula from high school: $$sin(a+b) = sin(a)cos(b) + sin(b)cos(a)$$ This lets us untangle the x […] what we want to do is find the derivative of this G of X and at first it could look intimidating we have a sine of X here we have a cosine of X we have this crazy expression here with a PI over cube root of x we're squaring the whole thing at first it might seem intimidating but as we'll see in this video we can actually do this with the tools already in our toolkit using our existing f′(x)=limh→0f(x+h)−f(x)h. Hence, (sin2x)′=limh→0sin2(x+h)−sin2(x)h=limh→ 0sin(2x+h)sin(h)h=limh→0sin(2x+h)⋅limh→0sinhh=(sin2x)⋅(1)=sin2x. We have only stated the rule here but it can easily be proved for all continuous, differentiable functions.
