Homework Equations
Q = CV
E = Q2/(2C)
E = 1/2*C*V2
I thought since they were parallel the voltage across each was the same so E = 1/2*36*106*302 but that gives me .0162 and that's not an option, .0016 is
Tomorrow I have an exam and my teacher gave us a hint to understand why the concentration to volume curve looks like the formula x2 but I can't find it anywhere's can someone take a quick second to explain.
C = mol/L
I have this question:

sin-1x=y & siny=x
tan-1x=y & tany=x
The answer is E but I don't know how my teacher got to that. Can someone explain this to me please?
Homework Statement
Having trouble understanding how to solve the derivative of y=x^tanx?
Like the question says. Can someone help me please? I have an exam tomorrow and having trouble solving these.

And I'm not asking for the answer. More of if someone can explain to me how to find voltage at time = 1

I know that V(t=0) is 20 and time = 1 and capacitance = .1
what I'm having trouble is finding V(t=1) to find dV/dt. Can someone help me?

V=I*R
I think they are almost the same but I'm not sure as to how to solve them...
for the second question I think it was just -.7 because the negative value would only count the Vd, and make it...
