the question and after the equation is separated (see p1.jpg)
p.s. y(0)=pi/2 ( i typed it wrongly. sorry)
i could not get the right answer.
suppose the answer should be (see p2.jpg)
pls help. I am quite confuse with the integration actually.

what do i need to do next to find the surface integral btw the planes z=1 and z=2?
or is there anything wrong that i did?

which one is correct?

i tried both, and both gives different answer.
one is 19/20 and another is 7/60

from the equation given, i change it into f(x,y).
how can i obtain the region of integration for x and y?
thank you.
just help me to check homework on vector calculus :)
Find the equation of the normal vector, tangent plane, and the normal line to
the graph of the equation at point P.
here's the equation and my solution:

i don't have the basic of analog, but i tried to look for in the books. unfortunately, the books are using voltage divider biasing instead of feedback biasing.
i have a circuit like this:

would anyone tell me the flow of the current in...
tq.
i want to ask another question:
is it possible to find the volume of the solid by double integration,
if only one equation is given
x/3 + y/4 + z/5 = 1
i know how to set up the DC sweep analysis, but what is it actually for?
i see both axes are voltages.
like transient analysis, i know exactly what it is for. it shows a time-domain voltage simulus.
hope for a brief description on it. thank you very much.
given f(x,y) = x-y
R is a triangle with vertices (2,9), (2,1), (-2,1)
then i need to find I,
I = int. int. (x-y) dx dy
i was taught to use this range when i do the dbl. integration
1 <= y <= 9
(y-5)/2 <= x <= 2
i want to ask, why can't i use this range:
1 <= y <= 9
-2...
tq. btw, i just found this in the internet.
# Infinity is encoded when the exponent field is all 1’s and the mantissa is all 0’s.
# If the exponent contains all 1’s but the mantissa does not contain all 0’s, then this is referred to as NaN or Not a Number.
sorry. it should be right, not rite. pardon me.
from your statement, i conclude that the exact answer should be infinity.
am i right?
what if, i have this floating point number : 11111111100000000000000000000000
and i am to convert this floating point number to decimal, the answer should...
thank you, but I am a bit confused.
im doing some self-study here, and the formula they wrote in the book is what i wrote in the first line.
btw, the x-axis is the axis of rotation.
nvm. i try to figure it out again :)
i need to write a report about the background material of a certain project. i am not good in english, so can anyone explain what exactly is needed? thank you.

i've look for the picture that shows the structure of HALL PROBE to complete my notes, but fail to find any clear diagram.
just hope that if any of you have a clear diagram on Hallprobe, hope can tell me.
thanks in advance.
the lifespan of a species of plant is a random variable T ( tens of days ). the probability density function is given by
f(t) = { (1/8)e^(-t/8) , t > 0
