thx for help everyone...hopefully i will be able to return the favour sometime in the near future... I am new to the site and atm it is mostly welcoming so once again thanks :)
What happens when you add two sin functions for example:
y=sin(x) + sin(2x)
***additional questions***
how about adding more than two funtions such as
y=sin(x+p/2)+sin(2x+p/2)+sin(3x+p/2)+sin(4x+p/2)+sin(5x+p/2)+sin(6x+p/2)+sin(7x+p/2)
