Need help!
An object moves along a straight line with position at time t given by s (t) = 3t cost . What is the velocity of the object at time t ? Ov(t) = -12+3 sint Ov(t) = 12+3 cos t - 3t sint Ov(t) = 12+3 sint Ov(t) = 12t3 cost + 3t sintUse the information given in the table to nd the following derivatives.

Round your answer to 3 decimal places. Student answer: Line 1: The variable here is 'w , but the method used to differentiate is the same as if the variable had been :1). Line 2: Recall that the derivative of y : cos :1: is y' = 7 sins: and the derivative of y = sin m is y' = cos a: . Line 3: Using the Product Rule, we get: Line 4: F' (10) = sin(sin w) + cos(cos 10) Line 5: To nd F' (g) we need to evaluate Fl (11)) at 'w : %. Line 6: Fl ('7) Z sin (sin g) -l- cos (cos 1) 4 - 1 1 sme)+wsStep by Step Solution
