Solution Summary: The author calculates the coordinates of P in the xy -plane when the value of theta =45° and the number of points in it.
Compute the distance from the point Q(4,-3,-5) to the plane 2x-3y+z-6=0. Round the distance to four or five decimal places. Using the formula in the from the picture
An insect is moving on the surface of a hot plate, the temperature of which at the point x units to the right of the lower left corner and y units up from the lower left corner is given by T(x,y)=100−x3−3y2. If the insect is at the point (1,3) in what direction should it move in order to maintain its temperature?
Show that the point (x0 , y0) closest to the origin on the line ax+ by =c has coordinates
