What is the integral of tan x sec2x with respect to x?
Homework Equations
The Attempt at a Solution
I have no idea as to how I should proceed!
As you were told in another thread, the "indefinite" integral is just the anti-derivative. It has nothing to do with a limit at infinity.hasan_researc said:How can that help? I have no idea!
Also, if we let u = tan x, then we get the limit of sin x as x tends to infinity, which is nonsense.
They're not contradictory. Use the identity tan2 x + 1 = sec2 x.hasan_researc said:The two answers are contradictory. Where's the problem?
Integration of trigonometric functions is a mathematical technique used to find the antiderivatives or integrals of trigonometric functions. It involves finding a function whose derivative is the given trigonometric function.
The process of integrating trigonometric functions involves identifying the type of trigonometric function (such as sine, cosine, or tangent), using trigonometric identities to simplify the function, and then applying integration techniques such as substitution or integration by parts.
Some common integration formulas for trigonometric functions include integrating sine and cosine as well as tangent and secant functions. For example, the integral of sine is -cosine, and the integral of tangent is natural logarithm.
Integration of trigonometric functions is useful in many fields of science and engineering, such as physics, astronomy, and structural design. It allows us to solve problems involving periodic functions and calculate areas, volumes, and other quantities.
Some tips for integrating trigonometric functions include using trigonometric identities to simplify the function, making appropriate substitutions, and being familiar with common integration formulas. Additionally, practicing and understanding the basic principles of integration can help in solving more complex problems involving trigonometric functions.
