Two sides and an angles are given. Determine whether the given information results in one triangle, two triangles , or no triangle at all. If there is one or more triangles solve any triangle(s) that results. If there is no triangle, show and provide an explanation why.
B = 106 degrees, b = 5, a = 23
A water wheel rotates through the angle x, the water level L behind the wheel changes according the equation "L = 1 - cos x - 2 sin^2 x" where L is measured in inches. Determine all values of x in degrees for which the water level is zero.
If sin (B) = -1/3 with B with B in Quadrant 3, find tan (B/2).
We know that the cos 60 degrees = 1/2. Show that the above is true using a half angle identity.
sec^(2)x+\csc ^(2)x=(\csc ^(2)x)/(\cos ^(2)x)
