Im not sure how to interpret the notation, specifically the one on the left, the one on the right seems like you just include everything in the universal set?
what does it mean when the line goes over everything? what does it even mean when the line is over the and/or symbol
Hi there, here's the question I am given, i will provide the answer that I think is correct, do you mind checking it and possibly pointing out where I am wrong if I am?
Give an example of a set S such that:
a) S is a subset P(N)
b) S belongs to P(N)
c) S belongs to P(N) and |S|=5
here...
The notation has me a bit confused...
Heres my logic
for the P({1}) on the inside
{EmptySet, {{1}}}
reason being, you always include the empty set, {1} is a part of the set. The cardinality is two
You have the set: {EmptySet, {{1}}}, and now you have to consider the outer "P"
the...

Re: usubstitution, definite integral, trig function
I wrote:
"I took the anti derivative of u, which came to (u^3)/3"
the part you are quoting is being misunderstood.
thanks everyone
Re: usubstitution, definite integral, trig function
im aware that the antiderivative is that, but what you are citing is me skipping a step and applying the fundamental theorem of calculus before entering the numbers.
problem: sin(x)^2cos(x)
integrate from 0 to pi/2the way I tried this is by making u = sin, and then working with du to make cos cancel out
the next thing I did was check my new intervals by plugging in pi/2 and 0 into the u function (becomes 0 to 1)
next, I took the anti derivative of u, which...
