3*x*5*sin(x) - E
((3*x)*5)*sin(x) - E
Differentiate term by term:
Apply the product rule:
; to find :
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:
; to find :
The derivative of sine is cosine:
The result is:
The derivative of the constant is zero.
The result is:
The answer is:
15*sin(x) + 15*x*cos(x)
15*(2*cos(x) - x*sin(x))
