If tan(a+b)=x and tan(a-b)=y find the values of tan2a and tan2b. | Trigonometric Ratios of Compound Angles | Trigonometry | Sci-Pi

If tan(a+b)= x and tan(a-b) = y, find the values of tan2a and tan2b.

answer:

When tan(A+B) = x and tan(A-B) = y, find the values of tan2A and tan2B.

You also need to remember the given formulas for the process.

This is how you find the values of tan2A and tan2B from tan(A+B) and tan(A-B).
