discoverer: anonymous I’m comparing answers to a friend’s and he has this…. 4/tan90 4/(1/0) (4 x 0)/1 4

shouldn’t tan90 be undefined?

  1. The problem is fine. The solution is wrong.
    tan90 is undefined.

  2. You are right tan90 is undefined as the tangent function is asymptotic.

    Therefore 4 / tan90 would be considered a mathematical error

  3. 4/[invalid imput] 4/1 divided by (1/0) 4/1 TIMES 0/1 4(0) / 1

    0

  4. You should copy another person’s homework.

  5. in this problem is not correct.final ans is 0.
