Consider the parametric equations below. x=t+cos(t), y-t-sin(t), Osts 2x Set up an integral that represents the length of the curve. Then use your calculator to find the length correct to four decimal places. Step 1 For a curve given by parametric equations x= f(t), y g(t), arc length is given by: dx - 1*√ (@)² + ( dt We have xt + cos(t) and yt-sin(t), 0 sts 2x. So, dx L = 1-sin t dx dy + dt Step 2 Now, remembering that sin?(t) + cos2(t)= dt. ✓1-sin (t) and -1-cos t dy dt dy dt = we have: √(1-sin(t))² + (1-cos(t))² 1- cos (t) sin(t) + cos(t).
