" If "x-(1)/(x)=2i sin theta," then "x^(4)-(1)/(x^(4))=

If x-(1)/(x)=2i sin theta, show that x^(4)-(1)/(x^(4))=2i sin4 theta

If x-1/x = 2i sin theta, "show that", x^(4)-1/x^(4)=2i sin 4 theta.

If 4x = sec theta and (4)/(x) = tan theta then 8 (x^(2) - (1)/(x^(2))) is

If x+i y=(1)/(1+cos theta+i sin theta) then x^(2)

If sin theta+cos theta=x, then (4-3(x^(2)-1)^(2))/(4)=

If sin theta+cos theta=x, then (4-3(x^(2)-1)^(2))/(4)=

tan theta+sec theta=x show that 2tan theta=x-(1)/(x),2sec theta=x+(1)/(x) hence prove that sin theta=(x^(2)-1)/(x^(2)+1)

If x cos theta - sin theta =1 , then x^2 + (1 + x^2 ) sin theta equals

If 4x = sec theta and 4/x = tan theta , then 8(x^2 -1/x^2) is
