Given z=cosx+isinx, show cosx=1/2(z+1/z)

We first consider 1/z=(cosx+isinx)^(-1). Application of De Moivre's theorem for integer n: (cosx+isinx)^(n)=cosnx+isinnx yields the result 1/z=cosx-isinx. Addition of the two forms z and z^(-1) steers us to ...

Find the roots of the following function: f(x)= 3*(x-1)^2 - 6.

In this question, we have to find the roots of f(x) or, in other words, its zeros. This means that we have to find all of the values of x for which f(x)=0. Therefore, the first step is to write down our equa...

Given the Earth orbits the Sun at a distance of 1.49*10^11m with Me = 5.97*10^24kg and Msolar = 1.99*10^30, what is the gravitational force between the Earth and Sun?

Using F = Gm 1 m 2 /r^2 and substituting in the values, we get F = 3.57*10^22N.
