The FASTER Solution Nobody Told You⏰

Hey, number ninjas! In this video, we'll uncover how to integrate sin^2 x faster than the integration by parts method! Here, we'll use a shortcut by remembering some key trigonometric identities to determine a direct identity we can use for sin^2 x, in case you haven't already memorized it, by using a combination of a few other famous and commonly memorized trig identities. This then becomes a much simpler u substitution integral to work with! For more quick tips and tricks, be sure to subscribe to the channel and leave a like if this was helpful to you. I hope you CRUSH your next ap calc exam like a ninja! - Number Ninja Dave
