How do you integrate 3ye^3z dz using u substitution?

In summary, the conversation is about integrating 3ye^3z dz using the u substitution method. The proposed solution is to use u=3z du=3dz and end up with yze^3z. However, it is pointed out that there is an extra factor of z in the solution. The correct solution is to differentiate ye^3z with respect to z, which gives 3ye^3z. Therefore, the final answer is ye^3z.

FAQ: How do you integrate 3ye^3z dz using u substitution?

What is the power of e?

The power of e, also known as the natural exponential function, is a mathematical constant that is approximately equal to 2.71828. It is often denoted as "e" or "exp(1)". It is a fundamental constant in calculus and is used to model continuous growth and decay.

How is the power of e integrated?

The power of e can be integrated using the formula: ∫e^x dx = e^x + C, where C is a constant of integration. This means that when integrating a power of e, the result will always be e raised to the power of the original function, plus a constant.

What are the applications of integrating a power of e?

Integrating a power of e is commonly used in various fields such as physics, finance, and biology to model growth and decay processes. It is also used in solving differential equations and in calculating probabilities in statistics.

Can the power of e be integrated using substitution?

Yes, the power of e can be integrated using substitution. This method involves replacing the variable in the function with a new variable, then integrating and substituting back the original variable. It is a useful technique for solving complicated integrals involving the power of e.

Are there any special integration rules for the power of e?

Yes, there are special integration rules for the power of e. One notable rule is the integration by parts, which involves splitting the function into two parts and applying the formula: ∫u dv = uv - ∫v du. This rule is especially helpful when integrating functions that involve the power of e multiplied by another function.
