Q: Find and simplify the second derivative of f(0) = cos(sin(30))

A:

Q: f (x) = 2x + 2/2 cos (x) For what values of x does the graph of f have a horizontal tangent?

A:

Q: √x √x + √√y = 1

A:

Q: Determine f " (x) a. f(x) = cot (4x) + csc (x) b. f(x) = sin2 (x) tan(x)

A: Given a. f(x)=cot4x+cscxb. f(x)=sin2xtanx

Q: cos(4x) cos(2x) sin(4x) sec(2x) 12. Verify: - sin(2x)

A: cos(2x ) =cos2(x)-sin2(x) = 2cos2(x)-1 =1-2sin2(x) sin(2x) = 2sin(x) cos(x)
