Atelevision camera at ground level is filming the lift-off of a space shuttle at a point 750 meters from the launch pad. let θ be the angle of elevation of the shuttle and let s be the distance between the camera and the shuttle (see figure). write θ as a function of s for the period of time when the shuttle is moving vertically. differentiate the result to find dθ / dt in terms of s and ds / dt.

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 bsuppose 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 cnow try a numerical problem. what is the direction of the vector w = < -1, 6 > ?
