4G 6:55 PM ...0.0KB/s ie I 68 ITE AUG27 DPP.d... ..x = 2 is a solution of the given equation. .. The number of solutions of the given equation is only one. EX. If 0<cos-x<1 and 1+sin (cos-l x)+ sin?(cos- x)+ sin (cos- x)+. .. 00= 2, then x equals 1 (В) 1 1 (A) 2 (a) (C) (D) 23 We have 1+sin (cos x) + sin? (cos- x) + ....... 00 =2 1 =2 = =1- sin (cosx) = sin (cos- x) = 1-sin(cos x > cos! х 6. Ans. EX. If tan- x+ tan-| x- = tan- then the value of 5x-4x+7 equals (A) 397 (B) 393 (C) 376 (D) 379 3 = tan- 6. We have tan-'x - tan- X- 3 X- х x+ X tan- 3 Y 1+ x+ = tan- X x* =9 X- Hence (5x* – 4x*+ 7) = 5(81)- 4(9) +7=405 - 36 +7=412 - 36 = 376. EX. If sinx+ siny= -1 and sin 2 cos 2y, then 1 dy = by= a. x= 8 2 64 12 C. x= 12 64 64 64 8. SOL. а, d.
