The total number of solution(s) of the equation 2 x + 3 tan ⁡ x = 5 π 2 in x ∈ 0,2 π is/are equal to

Options

  1. A1
  2. B2
  3. C3
  4. D4

Correct answer

C. 3

Step-by-step solution

2 x + 3 tan ⁡ x = 5 π 2 ⇒ tan ⁡ x = - 2 3 x + 5 π 6 y = tan ⁡ x and y = 5 π 6 - 2 x 3 Both the graphs meet exactly three times in 0,2 π . Thus, there are 3 solutions.
