1). Differentiate (x)sin x = (2xcosx+sinx)/2(x)

2). Differentiate 2t/(4+t^2) = (8-2t^2)/(4+t^2)^2

3). Differentiate (1-secx)/(tanx) = secx(-tan^2x + sec^2x)/(tanx)^2

4). Find equation of tangent line

y=(1+x)(cos x)

tangent line = y= x+1

5). If f(3)=4 g(3)=2 f'(3)=-6 g'(3)=5

A).(f+g)(3) = 6

B).(fg)(3) = 8

C).(f/g)(3)= -8

Note: (x) is supposed to be square root of x.
