It's far more exciting (and surprising, if you haven't seen this feature before), that C++11 takes the initialisation list @Borgleader wrote and constructs a Point from it for you. – Lightness Races in Orbit

WebThat's because the point going down into the negative quadrant. The original x point was on the positive side, so when you rotate it, it's going to the negative x. Let's take another example, still rotating it by -90 around the origin. This time, I'll use coordinates (-5,8) as my point. Like the pattern states, the coordinates will flip (8,5). WebFinal answer. Transcribed image text: (a) Find the coordinates of the points P and A. P (x;y) = ( A(x,y) = () (b) Use the coordinates of P and A to find the slope of the tangent line.
