Greetings All

I have the example below which produces 10 cycles
a = Sin[10 x]
Plot[a, {x, 0, 2 Pi}]

What Type of signal would I need to add/multiple/divide to reduce it's
signal/frequency to 5 cycles?  I know I can just change the number 10
to 5
but I need to combine it with another signal.  what mathematical
operation/signal do I need to use.
