STEP 1 Cannot integrate directly in this form, therefore use a trigonometric identity. Identity: sin(A) + sin(B) = 2sin((A+B)/2)cos((A-B)/2) STEP 2 (A+B)/2 = 3x             A + B = 6x   (1) (A-B)/2 = 5x  ...

Long term memory has been divided into two distinct memory subsystems, which are declarative (explicit, conscious) memory, and non-declarative (implicit, unconscious) memory. Procedural memory is an examp...

We can think of the constant term in a function in terms of x, for example in x^2 + 3x + 2 as 2 being multiplied by x^0. Anything to the power of 0 is equal to one, so in our example we would have 2 * x^ ...

Diagrams in IB Economics are a very important indicator to the examiner to quickly check if you know what you're doing. You can sound as smart as you want - mess up the diagrams, or don't use them, and yo...

No, absolutely not, especially not in IB. IB History is almost a debate class - they present you with a historical event and you need to make an argument for or against something. The way you write and th...
