IF (TANA+TANB)=M AND (TANA-TANB)=N, THEN COT(A-B)=?

If it is given tan(A-B) tanA-tanB/-1+tanAtanB and tanP-1/1+tanP=tan195 Find the value of P

prove tanA+tanB=sin(A+B)/cosAcosB

1 .If tanA=1/3 and tanB=1/7 (both A and B are acute),calculate 50sin(2A +B) 2.1Prove that sin2A+2c...

tanA+sinA=p, tanA-sinA=q shows that p^2+q^2

Prove: 1+(TanA/SinB)^2/1+(TanA/SinC)^2 = 1+(SinA/TanB)^2/1+(SinA/TanC)^2

If TanA=k.TanB prove that (k+1)sin(A-B)=(k-1)sin(A+B).

if tanB=3/4 then show that 3sin2B + 4cos2B =4

If secB=x,tanB=y(cosecA-cotA)=4/3,sinA+cosA=?

if tanA/tanB=k,prove that k+1/k-1=sin(A+B)/sin(A+B)

1+(tanA/sinB)²/1+(tanA/sinC)²=1+(sinA/tanB)²/1+(sinA/tanC)²
