Example Question #151 : How To Find Differential Functions
Differentiate the function:
Take the derivative of each term in the polynomial using the power rule where n is the exponent:
Example Question #341 : Differential Functions
Differentiate the function:
Take away the parentheses by multiplying the outside piece by each term within the parentheses so that you are left with a polynomial.
Then take the derivative of each term in the polynomial using the power rule where n is the exponent:
Example Question #343 : Differential Functions
A company wants to find the smallest amount of material to build a box with a square bottom of volume . Find the height of such a box.
None of the above.
To solve this problem, we must first know that the surface area of a box with a square bottom would be where is the length of the side of the box and is the height of the box.
The volume of the box can be found with the formula where is the length of the side of the box and is the height of the box.
We know that the volume of such a box must be equivalent to 6,250; therefore to solve this problem we must first solve one of the variables in terms of another.
Then we must plug it into the surface area equation.
Then, take the derivative and set it equal to zero to find the minimum. To take the derivative of that problem, one must know the power rule
.
Solving for
Plugging back into the original volume equation to solve for .

Example Question #152 : How To Find Differential Functions
Given that find
The first few derivatives can be evaluated to give a general trend:
Thus:
Therefore when :
Example Question #341 : Differential Functions
Differentiate:
To differentiate this function, you must use the chain rule. To do that, you first multiply the exponent by the coefficient in front of the expression. In this case, it's one. Then, you subtract one from the exponent, so at this point, you have .
The last step is to take the derivative of what's inside the parantheses, which is .
Multiply like terms so that your derivative is
Example Question #1372 : Calculus
Differentiate:
.
It might be helpful to rewrite this equation first: . Then, apply the chain rule.
First, multiply the exponent by the coefficient in front of the expression (in this case, 1).
Then, subtract 1 from the exponent.
Lastly, take the derivative of the expression.
This comes out to
.
Then, multiply like terms and get rid of the negative exponent:
.
Example Question #161 : Other Differential Functions
Find given the following function .
Since F(x) equals the integral of this function, F'(x) must then be the derivative.
The derivative is the integrand, of which we are taking the integral.
Evaluate the integrand at the bounds that you see for the integral. Doing this will give us the value of the derivative.
Example Question #349 : Differential Functions
Find the first derivative of the following function.
None of these
First recall the power rule which states that the derivative of is .
That makes the derivative of equal .
To find the derivative of the second part of the function we must use the multiplication rule. It states that the derivative of
is .
Using trigonometric derivatives we know the derivative of sine is cosine. Also, the rule associated for the derivative of is .
Thus the derivative of
is
so the final answer is
Example Question #161 : How To Find Differential Functions
Derive the derivative of .
None of these
The quotient rule states that the derivative of is .
The rules of trigonometric functions states that the derivative of sine is cosine and the derivative of cosine is negative sine.
The derivative of tangent is thus,
By the Pythagorean trig identities the above is equal to .
