Agreed but no one will upload it this evening I don't think. KPrime will be uploading it tomorrow though. I suggest just avoiding this discussion until KPrime uploads his solutions.
Where abouts will he be uploading it to? This thread or?
[QUOTE=Aerosmith;65983467]did you get tanx=3/4 for 5(i) or tanx=4/3?
After differentiating by using the product rule and letting dydx equal zero I got 3cos4x=4sin4x and dividing both sides by cos4x I got 4tan4x=3 so tan4x=3/4 so I'm worried why everyone is saying just tanx=3/4?

I think we would've included the 4, don't worry ahaha. I couldn't fully remember the question - I think it was tan4x but the 3/4 is all I needed to know. thank god
