In simple differentiation, we can use the fact that if y= x^n, dy/dx is equal to nx^(n-1). In other words, multiply the x term by the power, then decrease the power by 1. Here we have 2 terms so approach ...
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
