a) The value of as a function of "x" is
b) The rate of change of the angle with respect to x is -0.000308rad/m
Find the complete question and diagram attached
Form the right-angled triangle shown:
Adjacent side = x
Opposite side = 250m
angle of elevation =
Using the SOH CAH TOA identity
Hence the value of as a function of "x" is
b) If x = 450m
Differentiate both sides with respect to "x"
Substitute x = 450m and into the resulting expression to have:
Hence the rate of change of the angle with respect to x is -0.000308rad/m
