cos(x) sin(x) + ------ 2
sin(x) + cos(x)/2
Differentiate term by term:
The derivative of sine is cosine:
The derivative of a constant times a function is the constant times the derivative of the function.
The derivative of cosine is negative sine:
So, the result is:
The result is:
The answer is:
sin(x) - ------ + cos(x) 2
/cos(x) \ -|------ + sin(x)| \ 2 /
sin(x) ------ - cos(x) 2
