4) Create a maths problem and model solution corresponding to the following question: "Evaluate the following integral using trigonometric substitution" The integral should make use of the substitution x = atane, and also require a second substitution to solve. The square root component should be multiplied by a polynomial.

A rectangular tank 6 x 8 ft is filled with a gasoline to a depth of 80 ft. The pressure at the gasoline is 14.7 psi. Find the pressure at the bottom of the tank and force exerted on the bottom.

undefined 19 If we multiply a complex number z = reis by ei', we get ei®z = re (6+0), that is, a complex number with the same r but with its angle increased by e. We can say that the vector r from the origin to the point z= x+iy has been rotated by angle e as in Figure 7.4 to become the vector R from the origin to the point Z = X +iY. Then we can write X +iY = ei®z = ei® (x + iy). Take real and imaginary parts of this equation to obtain equations (7.12).
