int sin(2x+(pi)/(2))dx

int _ (- (pi) / (2)) ^ ((pi) / (2)) | sin x | dx

int(sin(2x))/(sin(x+(pi)/(6))sin(x-(pi)/(6)))dx

int_ (0) ^ ((pi) / (2)) (sin x) / (sin x + cos x) dx = int_ (0) ^ ((pi) / (2)) (cos x) / (sin x + cos x) dx = int_ (0) ^ ((pi) / (2)) (dx) / (1 + cot x) = int_ (0) ^ ((pi) / (2)) (dx) / ( 1 + time x) = (pi) / (4)

Show : int_(0)^((pi)/(2))sinxf(sin2x)dx=int_(0)^((pi)/(2))cosxf(sin2x)dx

int_(pi)^((pi)/(2)) sin|2x|dx

int e^(x//2) sin ((pi)/(4)+ (pi)/(2) ) dx =

If A=int_(0)^( pi)(sin x)/(x^(2))dx, then int_(0)^((pi)/(2))(cos(2x))/(x)dx, is equal to:

If x in(-pi,pi) then int sqrt(1+sin((x)/(2)))dx

int_(0)^(2)(|sin x|)/([(x)/(pi)]+(1)/(2))dx
