Derivative of :
...
HEY!! omg i need your help. im going to write it out now
...... are you sure?
\[(1/4 ) \sin^2 2 \theta\]
(1/4) 2(sin(2t)) cos(2t) 2 sin(2t) cos(2t) maybe?
what we have here is pretty much a composite of functions: C f(g(h(x)))
the constant C pulls out; and we peel off the layers to get to all the parts
C* f'(g(h(x))) * g'(h(x)) * h'(x) * x'
C = 1/4 h' = 2t' = 2 g' = sin(2t)' = cos(2t) f' = (sin(2t))^2' = 2(sin(2t))
2*2 = 4; /4 = 1; and we are left with sin(2t)cos(2t)
im honestly having issues with these types of problems, i feel bad , im learning this on my own, and im struggling. Idk how these work, and im constantly asking on here :/
i learned these on me own too
think of the chain rule like this if it helps: \[\frac{df}{dx}=\frac{df}{dg}*\frac{dg}{dh}*\frac{dh}{dx}\]
in order to derive for df/dx; you have to get thru all the derivatives that lead to it
wait what happened in the end?
ohh ok
what happened at what end?
i cant really say that i can keep up with this conversation to well :)
i was lost with the 2*2 /4 =1 that step just came at me and i didnt know what happaned. im still lost to be honest i feel like theres something i dont know. like my next question im looking at in fear
post!
no being scared. just remember the chain rule.
\[y= \sqrt{x} + 1/4 \sin(2x)^2 \]
its also finding the derivative. these type of problems are driving me insane, i feel like im missing some peice of information that is making this seem harder then it is
