In this question were given some information about a function for voltage. We have V of tea equals 120. Sign of 120. Hi, three. So we're finding out the amplitude. Well, we see the amplitude is going to be 1 20 So this is question A So amplitude is 1 20 the period we're looking at this horizontal compression. So we will divide to pie by 120 pie, which gives us 1 60 year. So a period is going to be 1/60 and now we're gonna graph two periods of this function. So we're starting at zero, and we're going down to negative 1 20 and up to positive 1 20 And then this would be 1/60. And here we have one 30th and then we're gonna graph this like, usual sine function. So we go up and down and then come up through 1/60 and then repeat. So we go up down on up through 1/30 and then this would continue. But here are two periods of this graph V. Now the next thing we're looking at is homes Law, where we have V equals I. You are where I is, Theo. The current and are is resistance. And in this example we have here we have V and are is 20. So in order to find the function for I were going to be dividing be by 20 so we can scroll down. So the divided by 20 is I of tea, which equals six. Because we have won 20 redivide by 20 we are left with six sign of 1 20 Hi t And now we're going to draw this function. So we have the amplitude, which is six. So the amplitude of six and a period of 1/60 because we have the same horizontal compression. So the period is one 60th Now when we here, I'll screw up a little bit. Now when we graph this, it's gonna look pretty similar to what we have above adjust with. Our new guidelines are new amplitude. We're just six instead of 1 20 And then we have 1/60 and one 30th they were gonna be drawing. That's pretty much the same just with these as our, uh, guidelines. So we come up and down and then through zero at 1/60. So that's the first period. And then we repeat up 3 1/30 on this would continue. But here we have two periods of our function. I of tea, which is six. Sign 1 20 high tea. So we've graft both I of t and V f t. So there are your answers.
