sin(1) 1 ------ + ------ x sin(x)
sin(1)/x + 1/sin(x)
Differentiate term by term:
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:
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:
The result is:
The answer is:
sin(1) cos(x) - ------ - ------- 2 2 x sin (x)
2 1 2*sin(1) 2*cos (x) ------ + -------- + --------- sin(x) 3 3 x sin (x)
/ 3 \ |5*cos(x) 6*sin(1) 6*cos (x)| -|-------- + -------- + ---------| | 2 4 4 | \sin (x) x sin (x) /
