Homework Statement
I don't understand why the x/2 is not being integrated. I would think one should use u substitution. u = x/2, du = x, but they're not doing that.
Trigonometric integration is a method used in calculus to find the integral of a function that contains trigonometric functions, such as sine, cosine, and tangent.
Trigonometric integration involves using specific trigonometric identities and substitution techniques to simplify the integral and solve it. Regular integration involves finding the antiderivative of a function using basic integration rules.
Some common trigonometric identities used in trigonometric integration include the double angle formula, half angle formula, and Pythagorean identities. These identities help to simplify and solve the integral.
Yes, trigonometric integration can be used for all types of trigonometric functions, including inverse trigonometric functions such as arcsine, arccosine, and arctangent.
Trigonometric integration is commonly used in physics, engineering, and other scientific fields to solve problems involving periodic motion, such as the motion of a pendulum or a vibrating string. It is also used in signal processing and electrical engineering to analyze and manipulate trigonometric waveforms.
