What is the derivative of minus one by X?
Answer: The derivative of 1/x is -1/x2.
What is the derivative of minus X?
Write down the function you will be differentiating. As an example, assume the function is e to the negative x, or y = e^(-x). Applying this to the function y = e(-x) gives the equation y’ = e^x *(-1), since the derivative of -x is -1 and the derivative of e^x is e^x.
What is the derivative of minus?
For what values of x is the sign of the derivative negative? Answer: When the sign of the derivative is negative, the graph is decreasing. The sign of the derivative is negative for all values of x < 0.
Is X 1 the derivative?
The derivative of x is just 1. Minus one is a constant. In other words, it does not change as the dependent variable changes. Therefore, its derivative is zero.
What is the derivative of 1 upon 1 minus x?
Differentiate. By the Sum Rule, the derivative of 1−x 1 – x with respect to x x is ddx[1]+ddx[−x] d d x [ 1 ] + d d x [ – x ] . Since 1 1 is constant with respect to x x , the derivative of 1 1 with respect to x x is 0 0 .
Is the derivative of x-1 equal to 1?
Derivative of x: The derivative of x is always equal to 1. Derivative of a constant: The derivative of a constant is always 0. Therefore, the derivative of x − 1 is equal to 1.
What is the derivative calculator?
The Derivative Calculator lets you calculate derivatives of functions online — for free! Our calculator allows you to check your solutions to calculus exercises. It helps you practice by showing you the full working (step by step differentiation).
What is the derivative of 1-1 with respect to X?
Since 1 1 is constant with respect to x x, the derivative of 1 1 with respect to x x is 0 0. Add 0 0 and d d x [ − x] d d x [ – x]. Since − 1 – 1 is constant with respect to x x, the derivative of − x – x with respect to x x is − d d x [ x] – d d x [ x]. Multiply. Tap for more steps… Multiply − 1 – 1 by − 1 – 1.
What is the derivative of sin (x)?
“The derivative of” is also written ddx So ddxsin(x)and sin(x)’both mean “The derivative of sin(x)” Examples Example: what is the derivative of sin(x)? From the table above it is listed as being cos(x) It can be written as: ddxsin(x) = cos(x) Or: sin(x)’ = cos(x) Power Rule Example: What is ddxx3?
