If `tanA+sinA=m and tanA-sinA=n`, then prove that `m^(2)-n^(2)=4sqrt(mn)`.

If tanA+sinA=p and tanA-sinA=q , then the value of ((p^(2)-q^(2))^(2))/(pq) is :

Express sinA and sec A in terms of cot A. OR If tan theta+sin theta=m and tan theta-sin theta=n , S.T m^(2)-n^(2)=4sqrt(mn)

If tanA=ntanB and sinA=msinB, prove that cos^2A=[m^2-1]/[n^2-1]

If tanA=m/(m-1)\ a n d tanB=1/(2m-1), then prove that A-B=\ pi/4

If tanA=sqrt2-1 then prove that sinA cosA=1/(2sqrt2)

If 8tanA=15 , find sinA-cosA

If sinA=3/5 , find cosA and tanA .
