Antiderivatives math problem

In summary, the integral of (2y^(1/2) - 3y^(2)) / 6y ; dy is equal to (2/3) √y - (1/4) y² + C. It can be found in number 34 and the provided link.

Find the following.
∫ (2y^(1/2) - 3y^(2)) / 6y ; dy
It's number 34 if you want to see it.Thanks.

I did
∫ [ ( 2√y - 3y² ) / ( 6y ) ] dy

= ∫ { [ (2√y ) / (6y) ] - [ (3y²) / (6y) ] } dy

= (1/3) ∫ ( 1/ √y ) dy - (1/2) ∫ y dy

= (1/3) [ 2√y ] - (1/2) [ y²/2 ] + C

= (2/3) √y - (1/4) y² + C ...... Ans.
Is that right?

Looks good to me. You can always check by differentiating it.
 

What is an antiderivative?

An antiderivative is the inverse operation of differentiation. It is a function that, when differentiated, gives the original function.

How do you find the antiderivative of a function?

To find the antiderivative of a function, you can use the rules of integration, such as the power rule, product rule, or chain rule. You can also use tables of known antiderivatives or integration techniques such as substitution or integration by parts.

What is the difference between an antiderivative and an indefinite integral?

An antiderivative is a function, while an indefinite integral is a mathematical expression that represents a set of infinitely many antiderivatives. In other words, an indefinite integral is a family of functions, while an antiderivative is a specific function within that family.

Can you have multiple antiderivatives for the same function?

Yes, a function can have infinitely many antiderivatives. This is because when we integrate a function, we add a constant of integration, which can take on any real value. Therefore, each different constant value will give us a different antiderivative.

What is the relationship between antiderivatives and definite integrals?

The definite integral of a function is the area under the curve between two specified limits. The antiderivative of a function can be used to evaluate definite integrals by plugging in the limits of integration and subtracting the results. This is known as the Fundamental Theorem of Calculus.
