If `cos e ctheta-sintheta=ma n dsectheta-costheta=n ,"eliminate"theta`

If tantheta+sintheta=mandtantheta-sintheta=n ,then

If x=cos e ctheta-sinthetaa n dy=cos e c^ntheta-sin^ntheta, then show that (x^2+4)((dy)/(dx))^2=n^2(y^2+4)dot

If a costheta+bsintheta=m and a sintheta-bcostheta=n," then Prove that " a^(2)+b^(2)=m^(2)+n,

(sintheta+sin2theta)/(1+costheta+cos2theta)

If x=sectheta-tanthetaa n dy=cos e ctheta+cottheta, then prove that x y+1=y-xdot

If pcos e ctheta+qcottheta=2 and p^2cos e c^2theta-q^2cot^2theta=5 then the value of sqrt(81 p^(-2)-q^(-2)) is________

If x=sectheta-costheta and y=sec^n theta- cos^n theta then show that (x^2+4)((dy)/(dx))^2=n^2(y^2+4)

If sin^(3) theta+sin theta cos theta+ cos^(3) theta=1 , then theta is equal to (n in Z)

If sintheta +costheta =1 then sin^6 theta +cos^6 theta is:
