Assignment:
The problem is read, set up and evaluate the definite integral for the area of the surface generated by revolving the curve. y=(x^4/8)+(1/4x^2),1 is less than or equal to t and t is less than or equal to 3, about the x axis.
Also there's a part b which reads.x=1-t^2,y=2t, 0 is less than or equal to t and t is less than or equal to 1, about the x axis.
Provide complete and step by step solution for the question and show calculations and use formulas.
