Best ResponseYou've already chosen the best response.1Looks like a good "paying attention" problem. What have you tried? This? \(\dfrac{d}{dt}2^{t}\cdot 2\cdot\sin^{1}(2t+1)\) Personally, I would rewrite it just a little. This? \(\dfrac{d}{dt}2^{t+1}\cdot\sin^{1}(2t+1)\)

Best ResponseYou've already chosen the best response.1Okay, so no extra 2 and there is no need or temptation to rewrite it. Great. You have the idea. Let's see what you get. Hint: \(\dfrac{d}{dt}2^{t} = 2^{t}\cdot\log(2)\)

Best ResponseYou've already chosen the best response.1Hint: \(\dfrac{d}{dt}\sin^{1}(t) = \dfrac{1}{\sqrt{1t^{2}}}\) That's about all you need.

Best ResponseYou've already chosen the best response.1\(\dfrac{d}{dt}f(t)\cdot g(t) = f(t)\cdot g'(t) + g(t)\cdot f'(t)\) Go!

Best ResponseYou've already chosen the best response.0product rules? but it does not make sense \[2^t \sin^{1} (2t+1) \] three parts. the product has two/ f(x)g(x)

Best ResponseYou've already chosen the best response.1If there where three, you could just group them and make pairs. There are only two. \(2^{t}\) \(\sin^{1}(2t+1) = asin(2t+1)\)

Best ResponseYou've already chosen the best response.0\[2^t*(asin(2t+1)'+(asin(2t+1)(2^t)'\] ?

Best ResponseYou've already chosen the best response.1There's that question again. Move forward. Do NOT stop to ask every time you flinch! Keep going!

Best ResponseYou've already chosen the best response.1Right. I understand your motivation. I am also telling you that it is holding you back. You have far too much fear. Learn the right things. Go the right direction. Go with confidence. What's next?

Best ResponseYou've already chosen the best response.0\[(2^t)(1/\sqrt(1t)*dx (2t+1)+asin(2t+1)(2^tlong(2)\]

Best ResponseYou've already chosen the best response.1So Close!! \(\dfrac{d}{dt}asin(t) = \dfrac{1}{\sqrt{1t^{2}}}\) \(\dfrac{d}{dt}asin(2t+1) = \dfrac{1}{\sqrt{1(2t+1)^{2}}}\cdot 2\)

Best ResponseYou've already chosen the best response.1See! That was very good. No need to fear. Just pay a little better attention.

Best ResponseYou've already chosen the best response.1Missed the "squared" in the square root. Otherwise, perfect.

Best ResponseYou've already chosen the best response.1Already showed you that. Pay better attention. \(\dfrac{2}{\sqrt{1  (2t+1)^{2}}}\)

Best ResponseYou've already chosen the best response.1Now, seriously. This is where I look you in the eye and ask you if you are in the right class, if you are truly dedicated to this course, if you think you can gain the confidence to move forward  and various other questions about your mental health. Work hard. You'll get it!
