x ___ e *sin(x) - 3*\/ x
d / x ___\ --\e *sin(x) - 3*\/ x / dx
Differentiate term by term:
Apply the product rule:
; to find :
The derivative of is itself.
; to find :
The derivative of sine is cosine:
The result is:
The derivative of a constant times a function is the constant times the derivative of the function.
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:
So, the result is:
The result is:
Now simplify:
The answer is:
3 x x - ------- + cos(x)*e + e *sin(x) ___ 2*\/ x
3 x ------ + 2*cos(x)*e 3/2 4*x
9 x x - ------ - 2*e *sin(x) + 2*cos(x)*e 5/2 8*x
