1. Integration by Parts Formula

The integration by parts formula is a fundamental technique used to integrate the product of two functions. The formula is as follows:

∫(u dv) = uv - ∫(v du)

This formula is essential for solving a wide range of integration problems, and it's a crucial tool to have in your Calculus 2 toolkit.

2. Trigonometric Substitution Formula

Trigonometric substitution is a powerful technique used to integrate functions that contain trigonometric expressions. The formula is as follows:

∫(f(x) dx) = ∫(f(sin(x)) cos(x) dx)

This formula is particularly useful when dealing with integrals that involve sine, cosine, or tangent functions.

3. Improper Integral Formula

Improper integrals are a type of integral that has infinite or semi-infinite limits of integration. The formula for an improper integral is as follows:

∫(f(x) dx) = lim(b→∞) ∫(f(x) dx) from a to b

This formula is essential for solving problems that involve infinite or semi-infinite limits of integration.

4. Parametric Formula

Parametric equations are a type of equation that uses a parameter to express the coordinates of a point on a curve. The formula for a parametric equation is as follows:

x = f(t) y = g(t)

This formula is particularly useful when dealing with curves that cannot be expressed as a function of x.

5. Polar Coordinate Formula

Polar coordinates are a type of coordinate system that uses a radius and an angle to express the coordinates of a point. The formula for polar coordinates is as follows:

x = r cos(θ) y = r sin(θ)

This formula is essential for solving problems that involve curves in polar coordinates.

6. Sequence and Series Formula

Sequences and series are a fundamental concept in Calculus 2. The formula for a sequence is as follows:

a_n = f(n)

The formula for a series is as follows:

∑(a_n) = a_1 + a_2 + a_3 +...

This formula is essential for solving problems that involve sequences and series.

7. Taylor Series Formula

A Taylor series is a type of series that is used to approximate a function at a given point. The formula for a Taylor series is as follows:

f(x) = f(a) + f'(a)(x-a) + f''(a)(x-a)^2/2! +...

This formula is particularly useful when dealing with functions that are difficult to integrate or differentiate.

8. Fourier Series Formula

A Fourier series is a type of series that is used to express a periodic function as a sum of sines and cosines. The formula for a Fourier series is as follows:

f(x) = a_0 + ∑(a_n cos(nx) + b_n sin(nx))

This formula is essential for solving problems that involve periodic functions.

9. Differential Equation Formula

Differential equations are a type of equation that involves an unknown function and its derivatives. The formula for a differential equation is as follows:

dy/dx = f(x,y)

This formula is essential for solving problems that involve rates of change and accumulation.

10. Vector Calculus Formula

Vector calculus is a branch of calculus that deals with vectors and their properties. The formula for vector calculus is as follows:

∇⋅F = ∂F_x/∂x + ∂F_y/∂y + ∂F_z/∂z

This formula is essential for solving problems that involve vectors and their properties.

In conclusion, mastering the top 10 Calculus 2 formulas is essential for success in your studies. By understanding these formulas, you will be able to tackle even the most challenging problems with confidence.
