I got it, kinda. The only difference is I got kPi/4 instead of kPi/2 and 5Pi/48 instead of 11Pi/48While you are technically correct you can get to the mentioned answer by using [imath]u=4x[/imath], then [imath]2\sin u = \sqrt{2-\sqrt{3}}[/imath], square both parts and use some trigonometric identities. Can you work out the rest?
I made a mistake, I know why it's supposed to be 11Pi, but what about kPi/4 instead of kPi/2I got it, kinda. The only difference is I got kPi/4 instead of kPi/2 and 5Pi/48 instead of 11Pi/48View attachment 32943

I've made the same mistake of getting the period of [imath]\frac{k\pi}{4}[/imath] instead of [imath]\frac{k\pi}{2}[/imath]. The error arose when we squared the equation :I made a mistake, I know why it's supposed to be 11Pi, but what about kPi/4 instead of kPi/2
Extraneous solution!!(there is a term for them, but I don't remember what it is).
Thank you!Extraneous solution!!
I call it corner time.Extraneous solution!!
Are you feeling lonely there - I am sitting here in the other corner - otis sent me here to keep you company....I call it corner time.
