Find the area of the region which is inside the parabola `y = - x^(2) + 6x - 5`, out the side the parabola `y = - x^(2) + 4x - 3` and left of the stragiht line `y = 3x-15`.

Find the area of the region which is inside the parabola `y = - x^(2)

1.	Find the area of the region which is inside the parabola `y = - x^(2) + 6x - 5`, out the side the parabola `y = - x^(2) + 4x - 3` and left of the stragiht line `y = 3x-15`.
Answer» Correct Answer - `73/6`

Consider the integral `I=int_(0)^(2pi)(dx)/(5-2cosx)` Making the substitution `"tan"1/2x=t`, we have `I=int_(0)^(2pi)(dx)/(5-2cosx)=int_(0)^(0)(2dt)/((1+t^(2))[5-2(1-t^(2))//(1+t^(2))])=0` The result is obviously wrong, since the integrand is positive and consequently the integral of this function cannot be equal to zero. Find the mistake.
