I give up, would you give me a hint?

Hi, this is my first post.  I know that:

Sorry I don't know how to do derivatives in LaTeX.
Can someone help me prove the above statement?

These are two coupled equations, to solve it differentiate both sides, to get:
y''=x'=y
x''=y'=x
The general solution to this, where C and D are constants, is C sinh(t) and D cosh(t).  Using your initial conditions:
x(0)=1
y(0)=0

x=cosh(t)
y=sinh(t).

Does this help?
