(2) f(x)=\sqrt(7-2x)
2.4 Find the limit.
(1) \lim_(x->1)(sin(x-1))/(x^(2)+x-2)
(2) \lim_(x->0)(sin4x)/(sin6x)
(3) \lim_(x->(\pi )/(4))(sinx-cosx)/(cos2x)
2.5 Suppose that w=u@v and u(0)=1,v(0)=2,u^(')(0)=3,u^(')(2)=4,v^(')(0)=5, and v^(')(2)=6. Find w^(')(0).
2.5 Differentiate
(1) y=\sqrt(secx^(3))
(2) f(x)=sin(cos(tanx))
(3) ,g(t)=((t-2)/(2t+1))^(9)
2.6 Two curves are orthogonal if their tangent lines are perpendicular at each point of intersection. Show that given curves
are orthogonal. Refer to 2.6 Homework #51, 52, 53.
(1) x^(2)+y^(2)=r^(2),ax+by=0
