" 6."(1)/(2-3cos2x)

prove that cos^(3)(2x)+3cos2x=4(cos^(6)x-sin^(6)x)

Prove : int sin x cos 2 x cos 3 x dx = - 1/4 ((cos 2x)/2 - (cos 4x)/4 + (cos 6x)/6) + c

If (x^2+1)/(2x)=cos theta then (x^6+1)/(2x^3)=

int_(0)^( pi/6)(sqrt(3cos2x-1))/(cos x)dx

(lim)_(x->0)((cos x)^(1//3)-(cos x)^(1//2))/(sin^2x) equals a. 1/12 b. 1/6 c. 1/3 d.1/2

If x in ((pi)/(6), (pi)/(3)) " then " int tan^(-1) sqrt((1 - cos 2x)/(1 + cos 2 x)) dx =

If: (1-cos2x)/(1+cos 2x)=3, then: x=

If: (1- cos 2x)/(1+ cos 2x)=3 , then: x =

cos^(-1)((x^(2))/(6)+sqrt(1-(x^(2))/(9))sqrt(1-(x^(2))/(4)))=cos^(-1)((x)/(3))-cos^(-1)((x)/(2)) hold for all x belonging to
