Differentiate term by term:
The derivative of sine is cosine:
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:
The derivative of a constant times a function is the constant times the derivative of the function.
There are multiple ways to do this derivative.
Rewrite the function to be differentiated:
Let .
Apply the power rule: goes to
Then, apply the chain rule. Multiply by :
The result of the chain rule is:
Rewrite the function to be differentiated:
Apply the quotient rule, which is:
and .
To find :
The derivative of cosine is negative sine:
To find :
The derivative of sine is cosine:
Now plug in to the quotient rule:
So, the result is:
The result is:
Now simplify:
The answer is:
2 2 2 + cot (x) + tan (x) + cos(x)
/ 2 \ / 2 \ -sin(x) - 2*\1 + cot (x)/*cot(x) + 2*\1 + tan (x)/*tan(x)
2 2 / 2 \ / 2 \ 2 / 2 \ 2 / 2 \ -cos(x) + 2*\1 + cot (x)/ + 2*\1 + tan (x)/ + 4*cot (x)*\1 + cot (x)/ + 4*tan (x)*\1 + tan (x)/
