You take the derivative using only one variable. The other variables act as constants.
you have to first find the derivative of the original function. You then make the derivative equal to zero and solve for x.
Derivative of a constantThe derivative of any constant is zero. This can be easily conceptualized if you think of the graph of any constant value. The derivative can be thought of as the slope of the line tangent to a curve at any given point. If you graph the expression y = 3, for example, it is just a horizontal line intercepting the y axis at 3. The slope of that line is, of course, equal to zero, for any point on the curve (which in this case is a straight line). Therefore, the derivative (with respect to x) of y = 3 is zero. Since the slope of any horizontal line is zero, the derivative of any line of the form y = k, where k is a constant, is zero.Answer2:Any constant quantity and an expression that has a maximum or minimum or both, has a derivative equal to zero.
The derivative of ANY constant expression - one that doesn't depend on variables - is zero.
"Pi divided by 2" is a number, i.e. a constant. The derivative is the rate of change. The derivative of any constant is zero, because a constant never changes.
The derivative of sin(x) is cos(x). Coefficients act like constants and always remain in derivatives. So, the derivative is -2cos(x).
The derivative of all constants is 0.
y is a sum of constants and so is itself a constant. Its derivative is, therefore, zero.
f(x) = c, where c is constant, has a derivative of zero.
x^0 = 1 for all x. The derivative of 1 is always zero.
The derivative of 3 x 2 , that is 6, is zero. The derivative of a constant number is always 0.
The derivative of 40 is zero. The derivative of any constant is zero.
2 x 2 = 4. 4 is a constant. The derivative of a constant is always 0. Therefore, The derivative of 2 x 2 is zero.
zero. In this problem, since there is no variable, the derivative is zero.
Zero. In general, the derivative of any constant is zero.
Yes.
The "double prime", or second derivative of y = 5x, equals zero. The first derivative is 5, a constant. Since the derivative of any constant is zero, the derivative of 5 is zero.
