If cos5 theta-a cos^(5)theta+b cos^(3)theta+c cos theta then c is equal to-

If cos 5 theta = a cos^(5)theta + b cos^(3)theta+c cos theta . Then, find the value of c.

If cos 5theta=a cos theta + b cos^(3)theta+c cos^(5) theta+d , then

If cos 5theta=a cos theta+ b cos^(3) theta+c cos^(5)theta+d , then

If cos 5theta=a cos theta+ b cos^(3) theta+c cos^(5)theta+d , then a. a=20 b. b=-30 c. a+b+c=2 d. a+b+c+d=1

If cos5 theta=a cos^(5)theta+b cos^(4)theta+c cos^(3)theta+d cos^(2)theta+e cos theta then which of the following is incorrect? (i)a=16(ii)b=5(iii)c=-20(iv)e=

cos5 theta=a cos theta+b cos^(3)theta+cos^(5)theta+d

lf cos 5theta-acos^5 theta + b cos^3 theta + c cos theta then c is equal to-

lf cos 5theta-acos^5 theta + b cos^3 theta + c cos theta then c is equal to-
