Prove each Trigonometric Identity
1. cot x secā“x = cot x +2 tan x + tanĀ³x
2. (sin x)(tan x cos x - cot x cos x)= 1 - 2 cosĀ²x
3. 1 + secĀ²x sinĀ²x=secĀ²x
4. sin x/1 - cos x + sin x/ 1 + cos x = 2 csc x
5. - tanĀ²x + secĀ²x = 1

The first few steps in solving the quadratic equation 9x2 + 49x = 22 ? 5x by completing the square are shown. 9x2 + 49x = 22 ? 5x 9x2 + 54x = 22 9(x2 + 6x) = 22 which is the best step to do next to solve the equation by completing the square? 9(x2 + 6x + 3) = 25 9(x2 + 6x + 3) = 49 9(x2 + 6x + 9) = 31 9(x2 + 6x + 9) = 103
