# The chain rule provides a method for taking the derivative of a function in which one operation happens within another. In function f (x) = sin (2x), the operation 2x happens within the sine function. If g (x) = sin (x) and h (x) = 2x, then g (h (x)) = sin (2x) = f (x).

The reason for this is because the derivative of sin 2 (x) is equal to sin (2x), which is what we just differentiated. The derivative of sin 2x is 2*cos 2x Approved by eNotes Editorial Team We’ll help your grades soar Start your 48-hour free trial and unlock all the summaries, Q&A, and analyses you need to get Learn how to solve differential calculus problems step by step online. Find the derivative of sin(2x). The derivative of the sine of a function is equal to the cosine of that function times the derivative of that function, in other words, if {f(x) = \\sin(x)}, then {f'(x) = \\cos(x)\\cdot D_x(x)}. The derivative of the linear function times a constant, is equal to the constant. Find the derivative of the function f(x) = 15x and x = 3 Find the derivative of x 2 - 3 at x = 2 Queries asked on Sunday & after 7pm from Monday to Saturday will be answered after 12pm the next working day.

When u=2x, then the expression is set into sin (u). Using the chain rule, the derivative of sin (2x) is 2cos (2x) Interestingly, the first derivative of sin (2x) is equal to the second derivative of sin2(x). The reason for this is because the derivative of sin 2 (x) is equal to sin (2x), which is what we just differentiated.

Definitionerna av derivata och integral baseras istället på x→0 sin2x ln(1+3x). = lim x→0 sin2x. 2x. ︸ ︷︷ ︸.

### (4.6). För att bestämma A1 och A2 måste funktionens värde och derivata vara bestämd i t = 03. Exempel: Bestäm funktionen y(t) som löser differentialekvationen.

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. Example 2. Differentiate the composite function f(x) = sin2 x.

In " Examples", you can see which functions are supported by the Derivative Calculator and how to use them. The derivative of sin (2x) is 2cos (2x), using the Chain Rule. Let u=2x. Then du=2.
