In the complex plane, the point corresponding to the complex z = sin2 + icos2 lies in the second plane______ Quadrant

In the complex plane, the point corresponding to the complex z = sin2 + icos2 lies in the second plane______ Quadrant

Since the terminal edge of angle 2 is in the second quadrant, so sin2 > 0, Cos2 < 0, so the point (sin2, Cos2) corresponding to the complex z = sin2 + icos2 is in the fourth quadrant, so the answer is four

In the plane rectangular coordinate system, after translating the line y = - 2x + 1 down four unit lengths, the analytical expression of the line is______ ．

From the meaning of the question: the translation of the analytical formula is: y = - 2x + 1-4 = y = - 2x-3

In the plane rectangular coordinate system, after translating the straight line y = - 2x + 1 down four unit lengths, what is the analytical formula of the straight line?

Y = - 2x-3 & nbsp; (formula: left plus right minus (change of independent variable), up plus down minus (change of whole function value))
