yeah well, that must be a problem, I got the information from my friend, I will check again tomorrow. Well, just a few questions and i think i can handle it from here: +HOw do you find b based on those information above? +For sine equation? a and d are still the same as at cosine equation? than...

I actually don't get what you mean So we have 14.5 cos10x+17.5, are we going to write sine equation that also concern to that cosine equation?

pi/2? is it right?

That's OK, thanks for helping me, there's a BOnus: Assuming still that the leftmost crest intersects the y-axis, write the sine equation to model the wave( this is require accounting for a horizontal translation) Would you help me where to start? Is it about the a going to be (-a)?

As you said, to find d, (32-3)/2=14.5, so the a going to be: 32-14.5= 17.5? Did i misunderstand something here?

So i got d= 14.5, a=17.5? I guess the equation is 17.5cos(bx)+14.5 Correct me if I'm wrong and what is b and how do i find it? Is it about vertical translation?

is the amplitude the highest point of wave from the x-axis? so the a going to be 35?

Homework Statement I have a problem, it's last major grade for my pre cal, it's about six flags and here's the information: H(min)(Trough): 3.ft H(max)(crest): 32 ft b= 10 ft period = 160 ft write a cosine equation to model of the wave Assuming still that the leftmost crest intersects...
