This, this and that Ah, but didn’t you sayed it was this? Ah, but didn’t you sayed it was this?
– This! This, this and that… oh, but weren’t that? That, that, this. This. That. I don’t understand anything more, you sayed that was that, then you sayed that was this. Eita that is this, that, this, that, this, this, that… That… Ah, then was this ê, your father
it’s a sin What was this? My hat! SINE,
what it is good for? Today’s Episode: Coordinate at the circunference
by center, angle and radius SINE,
what it is good for? If you gonna eat enchiladas, for nothing. Now, a engineer uses a lot… Really? Right in sight! Imagine, that you are a engineer that eated lots of cheese enchiladas Hum… Cheese… … and got your belly perfectly round If you got the values… of the center and radius, you can found any point that is in the belly, A.K.A., circunference. Gay…? No…! A.K.A. It’s abbreviation of Also Know As. Ah, show me please? Here? In public?? Here? In public??
– Yes! humm… O. K. After all, here at Ineptos Teachs, here you learn. Let me take this peace of coal that Oraculo used to teach how to Lighting the Grill. Follow me. Thanks Friday,
here at the neighborhood, there are always pieces of paper at the Wall, to encourage the kids to be creative. Well done, you mayor from this nameless city. Let’s see… You maybe know that what defines a circle, is that, it has a center… …and, any point in it is at the same distance from this center. I will draw part of a circle here, that you can call a arc… and you want to find a point. If you have a point here… I will project in
this axis that we will… here is our… X axis this stroke Note that… it didn’t have the same distance
from the radius Wow, how nice. Wow, for sure? Wow, like this, hein. But it has here To get this… diference is the reason we use cosine. You will take your X center and add it… with…
the cosine of that angle that could be thirty, forty five… And that formula Gives you the X of this point. And the radius? To find The Y point you use the same formula, but replaced the X center for the Y center And add to the sine of this angle. Thank you, Maestro Uaiquipidia. Always to the help.
