the derivative of the function would be
d/dx=−y/x2∗1/(1+(y/x)2)
= -yx^-2
Answer:
yes
Step-by-step explanation:
because both of them are horizontal straight lines
Ignore above
your equation is 2(cosx)^2-3cosx+1=0
use quadratic formula to get results
you will end up with
cosx=1 or cosx=1/2
so, x=0 or x=pi/3
