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
- A1
- B2
- C3
- 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.
