SOLUTION: Verify that each equation is an identity. {{{(tan(alpha+beta)-tan(beta))/(1+tan(alpha+beta)tan(beta))}}} =tan(alpha)

Question 675439: Verify that each equation is an identity.
=tan(alpha)

The left side of your equation matches the pattern of the right side of tan(A-B) with the "A" being and the "B" being . So it can be rewritten as a tan(A-B):

which simplifies to:

And we're done!
