Answer:

I hope you understand this question very well ok please mark as brainliest please it too difficult to solve it and also to be written so please mark as brainliest

Step-by-step explanation:

GIVEN F ' (x)=A SIN X + B COS X.

F ' (0)= 4 = A×0+B×1 = 4=B=4

F'(X)= A SIN X + 4 COS X

BR DEF., F ,(X) £ (A SIN X + 4 COS X)

DX = - A COS X + 4 SIN X + C.

NOW F(O)=3=-A +4×0+C=3

AND f( pie / 2)=5=-a×0+4×1+c=5=c=1

FROM (i) , - A + I =3=A=-2

F (X) - 2 COS X + 4 SIN -1 )
