oo r: - = oo: so the sequence n=l 2n 1- diverges.

X = 1 + 4t - t , y = 2 - t ; t = 1. = four- 2t, an d dy dx x t = dyldt dx I dt 2t + 1 . . t cos t + sm t = 4-3tz -Wh - 2t . en t 1 ' (x, y) = ( four, 1) and dy I dx = - ~, so an equa. t ion of the tangent to the curve on the aspect equivalent to t = 1 is y- 1 = -~(x- 4), oq/ = - ~x + 7. five. x = t cos t, y = t sin t; t = 1r. while t = 1r, (x, y) = ( -1r, zero) and dy Idx. = akin to t = 7. (a) x dy . dx . ' dy dy I dt t cos t + sin t -d = tcost+smt, -d = t(-smt)+cost,and-d = d ld = . . t t x x t -t s m t+cost = 1 + ln t, 1r - 1r I( -1) = 1r, so an equation of the tangent to U1e curve on the element is y - zero = 1r[x - ( -1r) ) , or y = 1rx + y = t2 + 2; x=l+ ln t = 1 ::} (1, 3).
