From: JEE Main 2019 (Online) 12th January Morning Slot
Question
Considering only the principal values of inverse functions, the set
A = { x 0: tan1(2x) + tan1(3x) = }
A = { x 0: tan1(2x) + tan1(3x) = }
Choose an option
Show full solutionCorrect option: D
Correct answer
Dis a singleton
Step-by-step explanation
tan1(2x) + tan1(3x) = /4
= 1
6x2 + 5x 1 = 0
x = 1 or x =
x =
x > 0
= 1
6x2 + 5x 1 = 0
x = 1 or x =
x =
x > 0
