What is the answer to this trig substitution problem (x^4)?
No, I haven't. How does that substitution help solve the problem?
By substituting x=4sin(theta), we can express everything in terms of theta and use trigonometric identities to simplify the integral. It also helps with the square root term since we can express that in terms of sin(theta) as well. Would you like me to walk you through the steps?
