Find the maximum and minimum values of the function g(0) = 30 – 8 sin(0) on the interval [0,π] Minimum value = Maximum value =

A cable hangs between two poles of equal height and 26 feet apart. Set up a coordinate system where the poles are 13, where x is measured in feet. The height (in feet) of the cable at position x is placed at x = -13 and x = h(x) = 18 cosh(x/18), where cosh(x) = (eª + e¯*)/2 is the hyperbolic cosine, which is an important function in physics and engineering. The cable is feet long.

Verify that sin(x+y)+sin(x-y)=2sinxcosy
