6. Graph y=sinx + cosx restricted to 0<=x<=pi/2. Locate the points on the graph at which the tangent line appears to have slope zero. Then find those x, 0<=x<=pi/2 , for which the function f(x)=sinx+cosx has a horizontal tangent line. (You need to solve the equation: f' (x)=0 for 9<x< pi/2 )

1- 4 Find derivatives. 1. d/dx(sinx + cosx + e^x) 2. d/dx(tanx - secx) 3. d/dx{secx9tanx + cosx)} 4. d/dx(cot x) sub|x=pi/4

Apply the quotient rule to f(x) = p(x)/q(x) and show that f′(0) = p′(0)/q(0) if p(0) = 0. Hence evaluate f′(0), wheref(x) =xe^2x/(2 − x)(1 − x)^2

By following the proof that d/dx e^x , show that for f(x) = a^x, d/dx a^x = f'(o)a^x.
