Acarpenter installs window units and wants a program which will calculate the amounts of wood and glass that needs to be purchased . he/she wants to just enter the dimensions of the window (in meters) and then get a display of the amount of wood and glass required. whilst glass is sold by the square meter, the wood supplier sells by the foot, so the amount of wood required must be given in feet and inches. furthermore, the width of the window must be between 0.5 and 3.5m inclusive and the height constrained between 0.5 and 2.0 meters inclusive. note that 1 meter = 3.25 feet and there are 12 inches in a foot.

I've been working on this for a few days and i just don't understand, it's due in a few hours. you. the direction of a vector is defined as the angle of the vector in relation to a horizontal line. as a standard, this angle is measured counterclockwise from the positive x-axis. the direction or angle of v in the diagram is α. part a: how can you use trigonometric ratios to calculate the direction α of a general vector v = < x, y> similar to the diagram? part b suppose that vector v lies in quadrant ii, quadrant iii, or quadrant iv. how can you use trigonometric ratios to calculate the direction (i. e., angle) of the vector in each of these quadrants with respect to the positive x-axis? the angle between the vector and the positive x-axis will be greater than 90 degrees in each case. part c now try a numerical problem. what is the direction of the vector w = < -1, 6 > ?
