Question

If tan (A+B)=1 and tan(A-B)= 1/√3 then find the value of a and b .....

Answer 1

A + B = 45

A - B = 30

Now by elimination method . Solve it.

Answer 2

Answer:

Tan45=1

So tan(a+b)=1

A+b=45 eq. 1

Tan30=1/root 3

A-b=30 eq. 2

Solve these by any method

Add eq. 1@2

A+b =45

+a-b=30

2a=75. i.e,A=75/2 similarly

Find b
