Using the fact, theta = inverse sin (h/6) and the drawing that a ladder (of 6 metre's long) is leaning up against a wall at a height of h and angle theta


The ladder slips down the wall at a constant rate of 0.05ms, find the rate at which the angle is changing in degrees and minutes when the height is 2.5m

thanks in advance

i think its more of a application of calculus rather then inverse trig.
