Title: How do I graph these? (sin and cos graphs)
Post by: Wrench on March 22, 2009, 12:52:21 PM

Problem 1: y= 2(cosx + 60 degrees)
Problem 2: y= 3(sinx - 90 degrees)
Problem 3: y= 2(sin3x + 60 degrees) - 1

I will make sweet love to anyone who can graph these for me.

i think that has a little too much slope. try again.

I did all of them but those three. The parentheses threw me off. I don't exactly suck at basic trig.

I didn't know how to properly distribute the number in front. Jesus Christ. Burn in Hell.

I laughed at this. You're so adorable.

I have a TI 84 Plus Silver Edition. It graphs it, but only shows the shape which is obvious.

You take the derivative to find where the slopes are zero.
