$n$th derivative of $\\sin^3x$ - Mathematics Stack Exchange
WebThe derivative of square root of sin x with respect to x can be calculated from first principle. According to the definition of the derivative, the differentiation of sin x can be written in limit form. Take y = f ( x). So, f ( x) = sin x, then f ( x + Δ x) = sin ( x + Δ x) d d x f ( x) = lim Δ x → 0 f ( x + Δ x) − f ( x) Δ x. WebIf x 2 + y 2 + sin y = 4, then the value of `(d^2y)/(dx^2)` at the point (–2, 0) is – 34.. Explanation: Given, x 2 + y 2 + sin y = 4. After differentiating the ... WebThe derivative of sine is cosine: Then, apply the chain rule.
