    Simpler way to graph multiple trig. functions?

    hey everybody,

    hope you enjoying maths

    so in class we are graphing functions like this: y = 3cos2x + 2sin3x + 1
    and we are supposed to draw 3cos2x and 2sin3x + 1 separately than add their y-values at certain x-values to get the first function. This is sometimes painstaking and very time consuming. I was thinking if anybody knows a simpler method to this?

    Much thanks

    I don't believe you are going to find any simpler method- except, of course, to use a graphing calculator.

    And, whether you do it by hand or use a use a calculator, be sure to use parentheses to write the function clearly. Is that
    2sin(3x)+ 1 or 2sin(3x+1)?
