If `cos(theta+phi)= mcos(theta-phi)`, then prove that `tan theta=(1-m)/(1+m)cotphi`.

If cos(theta+phi)=mcos(theta-phi) , then prove that tantheta=(1-m)/(1+m)cotphi .

If cos(theta+phi)=m cos(theta-phi) then tan theta is equal to

If cos(theta+phi)=mcos(theta-phi) then tantheta is equal to

If cos (theta +phi)=m cos(theta-phi) ,then the value of (1-m)/(1+m)cot phi .

If cos(theta+phi)=mcos(theta-phi) ,then tantheta is equal to a. ((1+m)/(1-m))t a n\ varphi b. ((1-m)/(1+m))t a n\ varphi c. ((1-m)/(1+m))cot\ varphi d. ((1+m)/(1-m))cot\ varphi

If theta+phi=45^(@) ,prove that (cot theta-1)(cotphi-1)=2

sin(theta+phi)/cos(theta-phi)=(1-x)/(1+x) then prove that tan(pi/4-theta)tan(pi/4+phi)=x

If 0

If cos theta = n cos ( theta + 2 phi) "show that"(n+1) tan ( theta + phi)= (n-1) cot phi
