Answer :  Let  & So, I = I1 + I2 + I3 …(i)

Solving I1, We know that,        I1 = 12 – 4 = 8

Solving I2, We know that,         I2 = 9 – 4 = 5

Solving I3, We know that,         I3 = 4

Putting the values of I1, I2, I3 in Eq. (i), we get

I = 8 + 5 + 4

= 17

OR

Let Apply the property      Now, let cosx = t

- sinx dx = dt

sinx dx = -dt

when x = 0,

then, cos (0) = t t = 1

and when x = π,

then, cos (π) = t t = -1  Now, we know that,        Rate this question :
