Y = cos(x)
sqrt(3)/2 = cos(30º)
dy = -sin(x)*dx
dy = -sin(30º)*(pi/180) = (1/2)*(pi/180)
y + dy = cos(x) - sin(x)dx
y + dy = sqrt(3)/2 - (1/2)*(pi/180) = 0.8573

Keep in mind x >0 since x is a measurement of length.
14 (inches) times 4 = 56 inches which would be 4.6 feet tall
Answer:
-1.362637
or if you round your answer -1.36
