Given that y varies directly to the square root of (x + 1), and that y = 1 when x = 8,(a)express y in terms of .x,(b)find the value of y when x = 3,(c)find the value of x when y = 5.

Find all the angles that satisfy the equation cos(θ)=32

If a and b are real numbers, then |a-b| is always, sometimes or never equal to |b-a| ?
