Calculus 1 / AB

1 week, 3 days ago

Okay, so here we got the following situation: we got a power triangle, we planked 5, another side of power 3 and a triangle we flanked 10 point. So i'm going to write like this 5 and 10, and we know that this angle here is pi. Over 3 point now, let me think of these 2 sides as 2 vectors so v and w. We need to find the length of this guy, which is w minus v point. Okay, so here we are going to use the dot product. Well, what do we have? We have that the length of w minus b is equal to square root of w squared minus 2 times the dot product between v and w, which is the length of v the length of multiplied by cosine of pi over 3, which is 1 half. So nothing here, plus the length o v slike this. So at the end, what do we get? We get square root of 100, minus 50 plus 25 point. So here we get square root of 75, which is 3 multiplied by 5 point. So the length of this guy here is to 3 multiplied by 5 and w.

In mathematics, precalculus is the study of functions (as opposed to calculus, which is the study of change, and algebra, which is the study of operations and their application to solving equations). It is generally considered to be a part of mathematics that prepares students for calculus.

In mathematics, a function (or map) f from a set X to a set Y is a rule which assigns to each element x of X a unique element y of Y, the value of f at x, such that the following conditions are met: 1) For every x in X there is exactly one y in Y, the value of f at x; 2) If x and y are in X, then f(x) = y; 3) If x and y are in X, then f(x) = f(y) implies x = y; 4) For every x in X, there exists a y in Y such that f(x) = y.
