2x/[(x+1)(2x-4)] = [A/(x+1) + B/(2x-4)]x = A(x-2) + B(x+1)x = -1-1 = A(-3)A = 1/3x = 2 2 = B(3)B = 2/3 therefore.... 2x/[(x+1)(2x-4)] ...

You find the area of the circle (using radius²* π). You divide your angle by 360 (or by 2π). You multiply the 2 answers and you find the area of the sector.

You factorise it. First, you find a common factor between a, b and c. Then, you find the 2 numbers that multiplied give you c and added give you b. If a=1, then the additive inverse of those 2 numbers ar...

 It is always important to be familiar with a variety of standard functions and their graphical representation, such as sine and cosine curves, as well as exponential, quadratic and other such functions. ...
