Not really sure how to approach this one: Consider the parametric equation: x=5[cos(theta)+(theta)sin(theta)] y=5[sin(theta)-(theta)cos(theta)] What is the length of the curve for theta=0 to theta= (9/2)pi Thanks

You're familiar with the formula , right? Make the appropriate substitutions. The integrand becomes t and the integration is therefore trivial ......
what was that formula? It showed up as "latex error: syntax error", thanks for the help! edit now i see it
