(sin x)/(sin x/8)=

(sin x)/(sin x)=lambda cos(x)/(8)-cos(x)/(4)cos(x)/(2), then lambda =

underset(x to 0)lim ((10 sin 9x)/(9 sin 10x)) ((8 sin 7x)/(7 sin 8x)) ((6 sin 5x)/(5 sin 6x)) ((4 sin 3x)/(3 sin 4x)) ((sin x)/(sin 2x))=

sin 4x sin 8x

sin 4x sin 8x

Evaluate the following limits: lim_(xrarr0)(sin5x)/(sin8x)

Evaluate: underset(xrarr0)lim(sin5x)/(sin8x)

Integrate the function int (4 cos x-3 sin x)/((8 sin x + 6 cos x)^(2))dx.

lim_(xrarr-7) ([x]^(2)+15[x]+56)/(sin(x+7)sin(x+8))= (where [.] denotes the greatest integer function)

lim_(xrarr-7) ([x]^(2)+15[x]+56)/(sin(x+7)sin(x+8))= (where [.] denotes the greatest integer function)

lim_(xrarr0)((10"sin"9x)/(9"sin"10x))((8"sin"7x)/(7"sin"8x))((6"sin"5x)/(5"sin"6x))((4"sin"3x)/(3"sin"4x))(("sin"x)/("sin"2x)) is equal to a) 63/(256) b) 1/(6) c) 6/(5) d) 1/(2)
