Hello please help me to solve this sum If tanA=2 ,tanB = 3 then find the value of (A+B)
GIVEN,tan A=2 A=tan-1(2)..............(1) [take it as equation no.1]AND,2tan B=3, B=tan-1(3).............(2) [take it as equation no.2] hence ,(1)+(2)= A+B=tan-1(2)+tan-1(3)
If tanA = 2 and tanB = 3 thentan(A+B) = tanA+tanB/1-tanAtanB = 2+3/1-2(3) = 5/1-6 = 5/-5 = A+B= tan-1(-1)A+B = General sol ,
TanA=2TanB=3Then,by formulaTan(A+B)=TanA+TanB/1-TanA TanBTan(A+B)=2+3/1-2*3Tan(A+B)=5/-(5)Tan(A+B)=-1Tan(A+B)=Tan(-45)(A+B)=Tan^-1(-45) ans...
Dear Student,tan(A + B) = { tan A + tan B }/{ 1 – tan A . tan B }= ( 2 + 3 )/( 1 – 2 x 3)= – 1 (Ans)So (A + B) = or Hope it helps!
If you have any more doubts, don’t hesitate, feel free to askI would be happy to help youAnd yes I forgot to mention that n is an integerso hope it helps!
