Y sin alpha=(1)/(2)p*T(a^(3)cos alpha-4cos^(3)alpha)=0

If sin alpha =(1)/(2) , prove that (3 cos alpha - 4 cos ^(3) alpha )=0.

sin alpha-cos alpha=(1)/(3) then sin^(4)alpha-cos^(4)alpha=

(sin 5 alpha-sin3alpha)/(cos 5 alpha+2 cos 4 alpha+cos 3alpha)=

prove that (sin alpha+sin3 alpha+sin5 alpha)/(cos alpha+cos3 alpha+cos5 alpha)=tan3 alpha

If cos y=x cos(alpha-y) then (1+x^(2)-2x cos alpha)*(dy)/(dx) is (A) sin alpha (B) -sin alpha (C) cos alpha (D) -cos alpha

The value of (sin5 alpha-sin3 alpha)/(cos5 alpha+2cos4 alpha+cos3 alpha) is

The value of (sin5 alpha-sin3 alpha)/(cos5 alpha+2cos4 alpha+cos3 alpha) is

sin alpha-sin2 alpha+sin3 alpha=4cos(3 alpha)/(2)cos alpha sin(alpha)/(2)

((cos alpha-cos3 alpha)(sin8 alpha+sin2 alpha))/((sin5 alpha-sin alpha)(cos4 alpha-cos6 alpha))=

If the line x cos alpha+y sin alpha=p touches the ellipse (x^(2))/(a^(2))+(y^(2))/(b^(2))=1 ,then the point of contact will be ((-a^(2)cos alpha)/(p),(-b^(2)sin alpha)/(p)) ((b^(2)cos alpha)/(p),(a^(2)sin alpha)/(p)) ((b^(2)sin alpha)/(p),(a^(2)cos alpha)/(p)) ( (a^(2)cos alpha)/(p),(b^(2)sin alpha)/(p))
