5*sin(x) - 4*tan(x)
5*sin(x) - 4*tan(x)
Differentiate term by term:
The derivative of a constant times a function is the constant times the derivative of the function.
The derivative of sine is cosine:
So, the result is:
The derivative of a constant times a function is the constant times the derivative of the function.
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:
So, the result is:
The result is:
Now simplify:
The answer is:
2 -4 - 4*tan (x) + 5*cos(x)
