1.) Estimate integral from (0 to 2) of 1/(2+x^2) dx using the midpoint rule
2.) Eliminate parameter of parmetric equation x=cos theta
y= sin ^2 theta
sketch the Cartesian graph equal to 0 less than or equal to theta less than or equal to sin pi/2
for -infinity less than t less than infinity
determine slope of lines tangent at each y axis crossing
Integrating using the Midpoint Rule; Eliminating Parameters and Slope of Tangent at Y-axis Crossings are investigated.
