If `2^7 cos^3 theta sin^5theta=asin8theta-bsin6theta+csin4theta+dsin2theta` and `theta` is real , then the value of `a+b+c+d` must be

If 2^(7)cos^(3)theta sin^(5)theta=a sin8 theta-b sin6 theta+c sin4 theta+d sin2 theta and theta is real,then the value of a+b+c+d must be

If 2^(7)cos^(3)theta sin^(5)theta=a sin8 theta-b sin6 theta+c sin4 theta+d sin2 theta and theta is real,then the value of a+b+c+d must be

cos theta-cos3 theta+cos5 theta-cos7 theta=4sin theta sin4 theta cos2 theta

If acos theta+bsin theta=4 and a sin theta-b cos theta=3 ,then find the value of a^(2)+b^(2)

int(2sin2 theta-cos theta)/(6-cos^(2)theta-4sin theta)d theta

(sin 3theta+sin5theta+sin7theta+sin9theta)/(cos 3theta+cos 5theta+cos 7theta+cos9theta) is equal to

lf 5 cos theta=7 sin theta , find the value of ( sin theta + cos theta)/(2 sin theta -3 cos theta) .

sin 7 theta * sin theta+sin11theta * sin 3theta= A) sin 4 theta * sin 10theta B) cos 4 theta * cos 10 theta C) sin 8 theta * sin 4 theta D) cos 8 theta * cos 14 theta
