sin^2 = . Next, we find m by taking the derivative, and then plugging in x = . We get:
= 3 (2 sin x (cos x) and thus m = 3 = 3. Therefore, the equation of the
tangent line is: y â = 3 .
- D Recall the definition of the derivative says: = fⲠ(x) and the derivative
of sec x is tan x sec x. Thus, = tan sec = = .
Therefore, the limit does not exist.
- A Using the Product Rule, u + v , take the derivative of f (x) and you get A.
- D Using the Chain Rule, = , take the derivative of f(x) and you get D.
- B First, use implicit differentiation to find :
2 x^2 y + 2 xy^2 = 0
Isolate and simplify:
Next, take the second derivative via implicit differentiation:
Plug in :
