(TCO 2) Find y': y = sin2(8x)

y' = 8 cos2(8x)

y' = 64 sin(8x) cos(8x)

y' = 16 sin(8x) cos(8x)

y' = 2 sin(8x)

Question 2. Question : (TCO 2) Find the derivative: y = -3x2 sec(2x)

Question 3. Question : (TCO 2) Find y' for

Question 4. Question : (TCO 2) Find f '(x) for y = 2 sin-1(3x)

Question 5. Question : (TCO 2) Find f '(x), f ''(x), and f ''(2) for f(x) = tan-1(2x)

Question 6. Question : (TCO 2) The voltage in a certain circuit is given by V = cos(224t) sin(244t), t in milliseconds and V in volts. How many volts per millisecond is the voltage changing at t = 4 ms? Use radian mode. Round your answer to 4 decimal places.

Week 6

(TCO 2) Find y’: y = log2(4x3)

Question 2. Question : (TCO 2) Expand using the rules of logarithms, then differentiate:

y = ln(3) + ln(x) – ln(3x) - ln(7),

y = ln(3) + ln(x) – ln(3x) - ln(7),

y = ln(3x) – ln(3x + 7),

y = ln(3) + ln(x) – ln(3x + 7),

Question 3. Question : (TCO 2) Find y’:

Question 4. Question : (TCO 2) ) Find y’ and y’’:

Question 5. Question : (TCO 2) Find the limit using L’Hospital’s Rule. Show the indeterminate form.

Question 6. Question : (TCO 2) The voltage in a certain circuit is given by V = -10e-tsin(224t), t in milliseconds and V in volts. How fast is the voltage changing at t = 4 ms? Use radian mode. Round your answer to 4 decimal places.
