" 1."(1)/(sin x+cos x)

The maximum value of cos x ((cos x )/( 1- sin x) + (1- sin x)/( cos x) ) is

( cos x )/( 1 + sin x ) + ( 1 + sin x)/( cos x) is equal to:

int_(-1)^(1)(sin x)^(5)(cos x)^(4)dx=

tan^(-1)((sin x)/(1+cos x))

int e ^ (x) (1-sin x) / (1-cos x) dx

Maximum value of cos x((cos x)/(1-sin x)+(1-sin x)/(cos x))

Solve: (cos x)/(1 - sin x) + (1 - sin x)/(cos x) =

tan ^ (- 1) ((sin x) / (1 + cos x))

If Delta (x)= |(1,cos x,1-cos x),(1+sin x ,cos x,1+sin x-cos x),(sin x,sin x,1)| , then int_(0)^(pi//2) Delta (x) dx= a) (-1)/(2) b) (1)/(2) c)1 d) -1

int(1+x)sin x+(1-x)cos x)dx
