Displacement: Find the function for the form y=2 sin(2x+c) that passes through (-π/8,

Hi I was wondering if someone could show me how this problem would be worked out. I missed a class due to illness and am having a hard time doing the rest of my homework. All of my homework problems are similar to this one and it would really help me if I could figure this one out first.

Problem:

Find the function for the form y=2 sin(2x+c) that passes through (-π/8, 0) and for which c has the smallest possible value then find a second function of the same form with a larger value for then sketch the two graphs together.

My question:

Would anybody be able to walk me through the problem step by step to help me understand how it is done?

Hi I was wondering if someone could help me with this example question that I have. I missed class due to an illness and am having trouble figuring out how to do this type of problem.

Problem:

Find the function for the form y=2 sin(2x+c) that passes through (-π/8, 0) and for which c has the smallest possible value then find a second function of the same form with a larger value for c then sketch the two graphs together

My question: Would anybody be able to walk me through the problem step by step to help me understand how it is done?

You are told that y=2 sin(2x+c) passes through (-pi/8, 0), so what is the first thing you can do? Hint: If any curve passes through a given point, then that point satisfies the equation.

Sure! Loads of people already have, online! For instance, this lesson explains the basic algebra for "transformations" or "translations" of functions, and this lesson explains how to do similar things with trig graphs. There are loads of other lessons, complete with pictures, available, too.

Once you have studied at least two lessons from the links, please attempt the exercise. If you get stuck, you can then reply with a clear listing of your thoughts and efforts, at which point we can help clear up any confusions. Thank you!
