it does not count but everyone got zero - 33.33% because
the questions are crazy
You cant use anything else except for the first principle to differentiate these
a) tan x
b) Ln x
c) e^x
"c" is probably the easiest one, some of us could do it.
The math teacher is being gay and said...
Minimum value for the desk
download the diagram from the attachment.
some are actually confused so you must download the picture.
Two corridors meet at right angles and are 2m and 3m wide respectively.
Θ is the angle marked on the given figure and ABCD is a desk
which must be kept...
1) a and b are variables related by the equation ab^3 = 40.
At the instant when a = 5, b is increasing at 1 unit per second.
What is happening to a at this instant?
2) A right angled triangle ABC has a fixed hypotenuse AC of length 10cm, and side AB increases at 0.1cm per second. At what...
given that
Θ = arctan 3/x - arctan 2/x
prove
dΘ/dx = (2 / x^2+4) - ( 3 / x^2+9)
hence find x when
dΘ/ dx = 0
incase you need an answer
ANS. x = root 6
All i need is prof of that thing... soo hardd -_-
DO NOT GIVE ME ANY LINKS..I NEED workingss.
thanks
