Question
Question: If f(x) = sin(sin x) and cot x f "(x) + f '(x) + g(x) cotx = 0, then g(x)...
If f(x) = sin(sin x) and cot x f "(x) + f '(x) + g(x) cotx = 0, then g(x)
A
–cos(cosx) sin2x
B
cos(cosx)sin2x
C
–sin(sinx) cos2x
D
sin (sinx) cos2x
Answer
sin (sinx) cos2x
Explanation
Solution
f "(x), f '(x) and substitute in the equation
therefore g(x) = cos2x.sin(sinx)
