Prove that for x is greater than or equal to 1:
arccos(1/x) = arcsin((sqrt(x^2 -1)/x)
Anyone know how to do this?

The curves C1 and C2 are defined by the following parametric equations:
C1: x=1+2t, y=2+3t, 2<t<5
C2: x=1/(2t-3), y=t/(2t-3), 2<t<3
Show that both curves are segments of the same straight line???
