This method will only work if your x term is divisible by 2. For example x2 + 6x + 12.
You then use the halved x term (e.g. 3x) to complete the square. The beginning of your factorisat...
To begin with, lets rewrite the equation in a way which is easier to understand by making y the subject and multiplying out the brackets:
y = x2 - 4x - 14
this looks significantly...
To tackle this problem, we will spilt the two terms given.
Firsly, we'll take the sin(x) by itself: d/dx (sinx) = cos(x) - where d/dx means the ...
A) dy/dx = (-4xy-2) / (2x2+4+pisin(piy) B) (62+3*pi) / (22+pi)
y=x^2
if y = a*x^b
then dy/dx = ba*x^(b-1)
therefore
dy/dx = 2*x
