Tangent sum and difference formula

WebSo everywhere we saw a y here, we can replace it with a -y. So this is going to be equal to tangent of x plus the tangent of -y, all of that over 1 minus the tangent of x times the tangent of -y. Well, we know the tangent of -y is the same thing as the negative tangent of y. And we know that over here as well. WebMar 20, 2024 · Sum and Difference Formulas for Tangent Tan (α – β) formula We know that, tan θ = sin θ/cos θ So, tan (α – β) = sin (α – β)/cos (α – β) = (sin α cos β – cos α sin β)/ …
