H/W prob. ans:
Domain : All students
P(x) : x students has taken more than 21 credit hours in a semester.
Q(x) : x received all A's
So,
∃x[P(x)^Q(x)]
I also got this...
Thoda doubt tha.about selecting the domain
Domain : All Students in the world.
P(x) : x student has taken more than 21 credit hours in a semester and received all A's.
Therefore, ∃x P(x)
What about this ?
so for exactly one student ( a student) it holds ? i thought it would need negation
Domain: All people
P(x): x is a student
s(x): x has taken more than 21 credits
q(x): x has received all "A"'
Ex(p(x)^s(x)^q(x))
is it correct?
plz reply I've an exam tomorrow
Neso is really changing way of learning. Thank you Neso...
"no large bird live on honey"... is it wrong to negate the Q(x) instead of negating the R(x)?
Domain-all student
P(x):x >21 credits in semester
Q(x):x has recieved 'A' in all subjects
-】(p(x)^q(x))
Domain: all people on the planet earth.
P(x): x is a student.
Q(x): x has taken more than 21 credit hours in a semester.
R(x): x has received all A's.
Ans: ∃ x [P(x) ∧ Q(x) ∧ R(x)]
"There exists x such that x is a student and x has taken more than 21 credit hours in a semester exam and x has received all A's."
Sir, Please complete the series of Data Structure and Algorithms as early as possible.
+1
They completed all but we need to pay rest of videos
Thank you, you are wonderful in your explanation, I'm studying this course at the university now, I benefit very much from you and wish you a little hurry to complete it
S(x) : is a student
M(x) : taken more than 21 credit hours
A(x) : received all As
∃x(S(x) ∧ M(x) ∧ A(x))
Going to cross 1 million soon
Sorry very soon.
Me ; " I don't understand anything ....
Neso : " Don't worry my child I'll teach you.."
Make videos on the computer organization & architecture
Ss .
Neso ❤️❤️❤️❤️❤️
You are a legend.
"isn't that so?"
Domain: Set of all the people on the planet
S(x) : x is a student
C(x): x has taken more than 21 credit hours in a semester
A(x): x has received all A's
∃x[S(x)^C(x)^A(x)]
Is this correct?
If not, please point out the error.
do dont have to take s(x) because x is already a student as you mentioned for C(x)..only take C(x) and A(x)...
@@codewithsankyy5738 Okay, thanks.
Why are you talking so fast?
Watch in 0.75x
Sir you said that Operating system and computer networks video are coming in app on 1st week of September. But you didn't upload it?why?
Because we’re testing the app, this time it is not a small project and it is taking little longer than our expectations.
@@nesoacademy how much time it will take?
Man, Neso academy is always there whenever I'm stuck. Thanks a lot guys!!
You are GOATED. Life saver.
1st view..
Apti videos are awesome
Thank you :)
Sir please complete discreet mathematics
Domain : All students
Let P(x) = x has taken 21 credits
Q(x) = x has received all A's
Answer to 5:45 = ∃x [ P(x) ^ Q(x) ]
birds that do not live on honey are dullin color
can also be written as there exist some bird that does not live on honey and are dullin color
this is nothing but blessings of god
Domain: All people.
S(x): x is a student.
P(x): x has taken more than 21 credit hrs in a sem.
Q(x): x has received all A's.
then
∃x (S(x) ^ P(x) ^ Q(x))
My answer is same. Is it correct? plz reply I've midterm exam tomorrow

Hello Sir Afaq.

Thanks
Thanks a lot
Thank you so much
Sir, can we write it as this way too? Hope you reply sir :)
Domain: All students
P(x) : "x has taken more than 21 credit hours in a semester."
S(x, y) : "x received y"
∃x[ P(x) ^ ∀y( S(x, y)) ]
You must define y,
Keep y as all A's not simple y
Did bracket matters
yes ofcos
Can we write like this : £ x p(x)
Where p(x): x has taken more than 21 credit hours in a semester and received all A's
All of my confusion is completely cleared!
