A curve has parametric equations:

x = 2 + t²                           y = 4t

Find the cartesian equation of this curve.

A cartesian equation of a c...

A stable solution is where neither player should move from their playsafe strategy, as it will only cause a decrease in profit.
Dominance is where one strategy is in every way better than another str...

Firstly we must change it into a form we can deal with. To do this we take the natural log (ln) of both sides.ln(y)=ln(a^x) ln(y)=x(ln(a))    using our rules of logsFrom here we differentiate. T...

For this we are going to test our knowledge of discriminats and factorisation. Firstly we will format the equation as (m+8)x²+8x+(m-7)=0From here we can see it takes the form ax²+bx+...

We know that for equation ax^2+bx+c=0
a = 2,b = 3,c = -5
If the roots x1 and x2 are real numbers:
x1 + x2 = -b/a = -3/2
x1*x2 = c/a = -5/2
