Derivative of Sin(6x)

We now understand the derivative of sin(6x). It is commonly represented as d/dx (sin(6x)) or (sin(6x))', and its value is 6cos(6x). The function sin(6x) has a clearly defined derivative, indicative of its differentiability within its domain. The key concepts are mentioned below: Sine Function: (sin(6x) is a transformation of the basic sine function). Chain Rule: Rule for differentiating composite functions like sin(6x). Cosine Function: cos(x), related as the derivative of the sine function.

The derivative of sin(6x) can be denoted as d/dx (sin(6x)) or (sin(6x))'. The formula we use to differentiate sin(6x) is: d/dx (sin(6x)) = 6cos(6x) The formula applies to all x.

We can derive the derivative of sin(6x) using proofs. To show this, we will use trigonometric identities along with the rules of differentiation. There are several methods we use to prove this, such as: By First Principle Using Chain Rule By First Principle The derivative of sin(6x) can be proved using the First Principle, which expresses the derivative as the limit of the difference quotient. To find the derivative of sin(6x) using the first principle, we will consider f(x) = sin(6x). Its derivative can be expressed as the following limit. f'(x) = limₕ→₀ [f(x + h) - f(x)] / h … (1) Given that f(x) = sin(6x), we write f(x + h) = sin(6(x + h)). Substituting these into equation (1), f'(x) = limₕ→₀ [sin(6(x + h)) - sin(6x)] / h = limₕ→₀ [2cos(3(2x + h))sin(3h)] / h Using the limit formula, limₕ→₀ (sin h)/ h = 1, f'(x) = 6cos(6x) Hence, proved. Using Chain Rule To prove the differentiation of sin(6x) using the chain rule, Consider f(x) = sin(u) where u = 6x. By chain rule: d/dx [sin(u)] = cos(u) * du/dx. Here, du/dx = 6. Thus, d/dx [sin(6x)] = cos(6x) * 6 = 6cos(6x).

When a function is differentiated several times, the derivatives obtained are referred to as higher-order derivatives. Higher-order derivatives can be a little tricky. To understand them better, think of a car where the speed changes (first derivative) and the rate at which the speed changes (second derivative) also changes. Higher-order derivatives make it easier to understand functions like sin(6x). For the first derivative of a function, we write f′(x), which indicates how the function changes or its slope at a certain point. The second derivative is derived from the first derivative, which is denoted using f′′ (x). Similarly, the third derivative, f′′′(x), is the result of the second derivative, and this pattern continues. For the nth Derivative of sin(6x), we generally use fⁿ(x) for the nth derivative of a function f(x), which tells us the change in the rate of change. (continuing for higher-order derivatives).

When x is a multiple of π, the derivative is 0 because cos(6x) is 0 at those points. When x is 0, the derivative of sin(6x) = 6cos(0), which is 6.
