Recent questions
How do you find the antiderivative of a constant?
By integrating a constant, the result is the constant times x plus c, where c is the constant of integration. This process involves adding x to the constant value to obtain the antiderivative.
What is the antiderivative of e dz?
The antiderivative of e dz simplifies to e times z plus c. This showcases that when integrating a constant like e, the result involves multiplying the constant by the variable and adding a constant of integration.
How do you integrate a variable raised to a constant?
Integrating a variable raised to a constant, such as x raised to the n, results in x raised to the n plus one divided by n plus one plus c. This pattern demonstrates how to integrate variable powers by increasing the exponent and dividing by the new exponent.
What is the antiderivative of x squared dx?
The antiderivative of x squared dx simplifies to x to the third divided by three plus c. This follows the pattern of integrating variable powers, where the exponent increases by one and is divided by the new exponent.
How do you find the integral of √(1 - x^2) dx?
To solve the integral of √(1 - x^2) dx, use trigonometric substitution by setting x = sin(θ) to simplify the expression to 3θ + c, then replace θ with inverse sin(x) to get 3 * arcsin(x) + c. This method allows for the integration of square root functions involving trigonometric identities.
