Question

Turunan pertama dari akar( cos x) + sin x.yg di dalam akar cuma yg ada d dlm kurung.terima ksih

Answer 1

= 

Turunan pertama : 
 + 
= 
=

Answer 2

 f(x) = V(cos x) + sin x

f(x) = cos^(1/2) x + sin x

f'(x)
= 1/2 . cos^(-1/2) x . (-sin x) + cos x
= -1/2 . (sin x)/(cos^(1/2) x) + cos x
= -1/2 . (sin x)/V(cos x) + cos x
= -(sin x)/(2 V(cos x)) + cos x
