Round to the nearest three decimal places. I'm not sure if i should take the derivative and then solve for 0. Using critical values. I'm very confused and my notes are no help.

In the equation y = kx, k represents the ____________________. A. constant of change B. variability quotient C. scalar D. constant of variation

I tried solving it using a graphing calculator and by using a triangle with SohCahToa, and I believe the answer is 2/(45^(1/2)) but am told it's wrong. Please help?

1.prove each identity sin (q)/1+sin (q)-sin q/1-sin(q)=-2 tan^ 2 (q) 2.(cos^2 q/1-sin q )- (cos^2/1+sin q)

whose solve this problum as early as possible

1.Determine the value of the central angle for θ for 0 q<2π 2.Determine the values of the central angle for θ for-2π q>4π
