1 :5 Consider the definite integral f tilt: u {2:2 _ g)? This can be transformed into a basic integral by letting ti = I I and in = I Ids: Performing the substitution yields the integral h .. f | Ian 5 ' .. where a = I I and b = I I \fEvaLuate the integral below by interpreting it in terms of areas in the gure. The areas. of the Labeled regions are A1= 5, A2=3, A3=1 and A4=2 1g [figure is NOT to scale}
