dy/dx = dy/dt *dt/dx (chain rule).
x=4tan(t) hence dx/dt = 4 sec2(t)
y = 531/2sin(2t) hence y'= 1031/2 cos(2t)
therefore dy/dx = 103...
a) Need to multiply with conjugate to bring z to form a+ib. => z= z * (1-i)/(1-i) = (4-4i) / 2 = 2-2i
b) z^2 = (2-2i)^2 = 4-8i+4 i^2 = 4-8i-4 = 8i
since z is root of x^2+px+q=0 then z* (c...
To find the first derivative we must apply the chain rule. Our aim is to find dr/d(theta). We start by bringing the differential of what's inside the sine brackets outside and multiplying it by the differ...
One criticism of the functionalist based explanations of crime and deviance is that functionalists rely on a pattern of crime shown in official crime statistics. However, a lot of crime is never actually ...
