Help finding integral of trigonometric function

Click For Summary
SUMMARY

The integral 4∫tan(x^2)dx from 0 to √(π)/2 presents significant challenges due to the complexity of integrating trigonometric functions of x^2. Attempts at u-substitution and finding relevant trigonometric identities have proven ineffective. Alternative methods suggested include converting the function into a ratio of sine and cosine for integration by parts or utilizing exponential forms. Given the nature of the problem, reviewing notes on similar functions is recommended for effective problem-solving.

Homework Equations



4∫tan(x^2)dx from 0 to √(π)/2

The Attempt at a Solution



I tried doing u-substitution, which didn't work, and also tried to look for a trig identity and wasn't able to find any relevant one.

Have you tried changing it to a ratio of sine and cosine and integrating by parts?
How about changing it to exponential form and tackling that?

in general trig functions of x^2 are pretty nasty.
If this is part of an exercise you should look to your notes about similar functions.
If not you may want to consider working your actual problem by another means.
