Question

Ssinx/(sin(x+a)) dx
O (a) xcosa-sina log|sin(x+a)+c
O (b) log |secx |+C
O (c) log|xl+c
O (d)
(d) cos x + C

Answer 1

Step-by-step explanation:

sin(x−a)

=

cos(x−b)

sin(x−b+(b−a))

=tan(x−b)cos(b−a)+sin(b−a)

∫

cos(x−b)

sin(x−a)

dx=cos(b−a)∫tan(x−b)dx+sin(b−a)∫dx=cos(b−a)log∣sec(x−b)∣+sin(b−a)x+C

B=sin(b−a)
