Find a numerical value of one trigonometric function of x for csc x =sin x tan x + cos x. a. sin x =0 c. sin x =1 b. cot x +0 d. cot x =1

  d.  cot x =1

Step-by-step explanation:

The equation contains undefined values for x=0 or π/2. The only answer choice that corresponds to something different is ...

  d. cot x = 1

__

This condition is true for x = π/4. Then the equation becomes ...

  csc(π/4) = sin(π/4)tan(π/4) +cos(π/4)

  √2 = (√2/2)(1) +(√2/2) . . . true
