Hey, i was wondering if a flat battery (the types which are used in remote controls etc) would charge if left in sunlight. Also, what does 'trickle charge' mean, i've seen it written on my battery charger, but i don't know what it means. Thanks in advance!

lim (e^x + x)^(1/x)
x->0

and

lim (1 + (1/x^2))^x

I think both of these are supposed to b solved by using L'hopital's rule, but I cant seem to get the answer. Any help will be appreciated.

here's some problems i dont understand

it says

find derivatives implicitly-
x^3 - xy + y^2 = 4

x^ 1/2 + y^ 1/2 = 9

x^3 - 2x^2y + 3xy^2= 38

xy^2 -2y= e^x

x^2 = 36 + 4 y^2

x^2 = SIN y
