*Answer can only contain numeric values
JEE Main Maths Mock Test- 6 - Question 21

The number of solutions of the equation tan2x –sec6x + 1 = 0 in [0, 4π] is :-


Detailed Solution for JEE Main Maths Mock Test- 6 - Question 21

sec6x = 1 + tan2x ⇒ sec6x = sec2x
if |secx| > 1 then sec6x > sec2x
Hence only possible solution is sec2x = 1 ⇒ x = nπ
Hence in [0, 4π] possible solutions are 0, π, 2π, 3π, 4π

*Answer can only contain numeric values
JEE Main Maths Mock Test- 6 - Question 22

 

If solution of equation 3cos2θ – 2√3 sin θ cos θ – 3sin2θ = 0 are nπ + π/r and nπ + π/s then |r – s| is equal to:-


Detailed Solution for JEE Main Maths Mock Test- 6 - Question 22

Equation can be written as
3tan2θ + 2√3 tanθ – 3 = 0
⇒ tan θ = 1/√3 and tan θ = -√3
⇒ θ = nπ + π/6 or θ = nπ – π/3
⇒ |r – s| = |6 + 3| = 9

*Answer can only contain numeric values
JEE Main Maths Mock Test- 6 - Question 23

If (x1 – x2)2 + (y1 – y2)2 = a2 ;
(x2 – x3)2 + (y2 – y3)2 = b2 ;
(x3 – x1)2 + (y3 – y1)2 = c2  and
= (a + b + c)(b + c – a)(c + a – b)(a + b – c)
Then the value of k is :-
