________ cos(2*x) + \/ sin(x) - 1 ------------------------- ___ tan(x) - \/ 3
(cos(2*x) + sqrt(sin(x)) - 1)/(tan(x) - sqrt(3))
Apply the quotient rule, which is:
and .
To find :
Differentiate term by term:
The derivative of the constant is zero.
Let .
Apply the power rule: goes to
Then, apply the chain rule. Multiply by :
The derivative of sine is cosine:
The result of the chain rule is:
Let .
The derivative of cosine is negative sine:
Then, apply the chain rule. Multiply by :
The derivative of a constant times a function is the constant times the derivative of the function.
Apply the power rule: goes to
So, the result is:
The result of the chain rule is:
The result is:
To find :
Differentiate term by term:
The derivative of the constant is zero.
Rewrite the function to be differentiated:
Apply the quotient rule, which is:
and .
To find :
The derivative of sine is cosine:
To find :
The derivative of cosine is negative sine:
Now plug in to the quotient rule:
The result is:
Now plug in to the quotient rule:
Now simplify:
The answer is:
