1 2*t*sin(4*x) + - x
(2*t)*sin(4*x) + 1/x
Differentiate term by term:
The derivative of a constant times a function is the constant times the derivative of the function.
Let .
The derivative of sine is cosine:
Then, apply the chain rule. Multiply by :
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:
The result of the chain rule is:
So, the result is:
Apply the power rule: goes to
The result is:
The answer is:
1 - -- + 8*t*cos(4*x) 2 x
/1 \ 2*|-- - 16*t*sin(4*x)| | 3 | \x /
