What is the derivative of 3 x?

Calculus Examples Since 3 is constant with respect to x , the derivative of 3x with respect to x is 3ddx[1x] 3 d d x [ 1 x ] .

What is the derivative of 1 by X Square?

Explanation: We will use the power rule, which states that the derivative of xn is nxn−1 . We can use the power rule once we write 1×2 as x−2 . Thus, according to the power rule, the derivative of x−2 is −2x−2−1=−2x−3=−2×3 .

What is the differentiation of x minus one upon x 1?

Differentiate. By the Sum Rule, the derivative of x−1 x – 1 with respect to x x is ddx[x]+ddx[−1] d d x [ x ] + d d x [ – 1 ] .

What is the differentiation of x sin x?

Hence, the derivative of xsinx comes out to be xcosx+sinx.

How do you calculate derivative?

The first step to finding the derivative is to take any exponent in the function and bring it down, multiplying it times the coefficient. We bring the 2 down from the top and multiply it by the 2 in front of the x. Then, we reduce the exponent by 1. The final derivative of that term is 2*(2)x1, or 4x.

  • A useful mnemonic for the numerator of the derivative is “Down-dee-up,up-dee-down,” since the minus sign means the order matters.
  • For example,consider the function f ( x) = x 2+2 x − 21 x − 3.

    How do you find the derivative of an inverse function?

    The first method consists in finding the inverse of f and differentiate it. To find the inverse of f we first write it as an equation. y = (1/2) x – 1. Solve for x. x = 2y + 2. Change y to x and x to y. y = 2x + 2. The above gives the inverse function of f.
