Class XII

If ∫f(x) f x dx = g (x) + C and also ∫f(x) f x dx = h(x) + D, then
  1. g (x) . h (x) = constant
  2. g(x)/h(x)=constant
  3. g (x) - h (x) = constant
  4. h (x) + g (x) = constant
If∫g(x)dx=g(x),then∫g(x)[(1+sin x)/1+cos x)]dx is equal to
  1. g(x)/[1+cos x]
  2. g (x)[ tan x/2] + C
  3. (1/2) g(x) ( sec²) x/2
  4. g(x) tan x + C
∫(tan x+cot x) dx is equal to
  1. log | sin x + cos x|+C
  2. log | cot x|+C
  3. log | tan x|+C
  4. None of these
∫(cos x/cos(x−a) dx is equal to
  1. sin a – sin a log | cos ( x – a) |
  2. sin a – sin a log | cos ( x – a) |
  3. x cos a+sin a log | cos (x–a) | + C
  4. x cos a – sin a log | cos ( x – a) |
