What is Pythagorus Theorem ? Find the length of BC if given a right angle triangle ABC where AB is 8cm and the length of the hypotenuse AC is 10cm ?

Pythagorus Theorem states that the side of a 'Right Angled Triangle' can be found by using the formulae c 2 = a 2 + b 2 , where c is considered as hypotenuse. In our case the hypotenuse is AC and by putting ...

Determine the coefficient of y^3 in the binomial expansion (2x-3y)^4

Using the method of binomial expansion (which I will cover in more detail) we get (2x-3y)^4 = + 1(2x)^4(3y)^0 - 4(2x)^3(3y)^1 + 6(2x)^2(3y)^2 - 4(2x)^1(3y)^3 + 1(2x)^0(3y)^4 = = 16x^4 - 96x^3 y + 216x^2 y^2 ...

Solve: 5x - 2 > 3x + 11

5x - 2 > 3x + 11 5x - 3x > 11 + 2 2x > 13 x > 13/2 x > 6.5

Q = P/ R (4 – t) Calculate the value of Q when P = 36, R = 3 and t = –2

First list what the question gives you. p=36 r=3 t=-2 Sub in the values that you know into the equation. Q= 36/ 3(4--2) Q= 36/18 Q=2

Solve the differential equation: dy/dx = 6x^2 + 4x + 9

dy/dx = 6x 2 + 4x + 9 dy = (6x 2 + 4x + 9) dx integrating gives: y= (6x 3 /3) + (4x 2 /2) + 9x + c y= 2x 3 + 2x 2 + 9x + c If given boundary conditions of y(0)=0 then 0 = 2(0) 3 + 2(0) 2 +9(0) +c therefore c...
