Re: Utp ict

To say that every course offered in UTP is related to the oil and gas industry is quite a conceptual error. While it is true that graduates in UTP are more exposed to the oil and gas industry due to...

Re: STPM Maths T help

For ques 2, answer should be 0.65

working.. Just take out e^-x

[e^-x ( e^2x -2)] / [e^-x (2e^2x +1) ] = 1/5

Cancel the e^-x. you will get

(e^2x -2)/(2e^2x +1) = 1/5
a few more steps...

Re: STPM Maths T help

Third question is quite easy:
log3 x^2 + log3 x = log9 27
3log3 X = (log3 27)/(log3 9)
= 3/2
log3 X = 3/6
X= sq rt (3)
:P

Re: STPM Maths T help

(3^x+1)(4^x+2) = 5^x+3
[3(3^x)][4^2(4^x)] = 5^3(5^x)
48(12)^x = 125(5^x)
48 = (5 )^x
125 (12)

Then solve using lg (48/125) / lg (5/12) = x

Re: STPM Maths T help

1) A + B = 2+1 + (3-1)i = 3 + 2i
2) AB = (2-i)(1+3i) = 5 + 5i

modulus = (25+25)^1/2 = (50)^1/2 simplify

3) A-iB = 2-i-i+3 = 5-2i
1+iB = 1+i-3 = -2+i

therefore A-iB over 1+iB = (5-2i) over...

Re: STPM Maths T help

This look quite easy honestly..

1. Using my brain, the ans is 3 + 2i . Jz do it like algebra.

2. AB = 2 +5i + 3 (note: i square wouuld be -1 as i = sq root -1 )
AB = 5+5i
Thus, the modulus...

Re: STPM: Math T/S Paper 1 Integration

Another method which I find quite useful teaching students is:

Let 2^x = a and 5^y = b

Therefore a - b = 3

and a/8 + b/4 = 21

I'm sure you can solve this =) just don't forget to find x...

Re: Physical Chemistry

cause PV = k, where k is a constant. Therefore, under the standard temperature, the product of pressure and volume will be the same regarless tothe variation in quantity for P and V.

That is why,...

Re: STPM Physics Question Help!!!

Hint:
a/V^2m has the same unit as pressure;
b has the same unit as molar volume.

The equation is originated from PV=nRT. Comparing them will give you the idea how to get answer.

Hope that...
