t 3. Consider a curve in R3 parametrized b t = (15,132 + 1, y 'Y( ) ,4t2 + 1 area under the curve. (Note: When we project the curve onto the anyplane, the curve sweeps through a surface. The area under the curve means the area of this surface. Hint: Interpret this as a scalar line integral.) ) where O S t S 2. Find the
