Front

What is the formula for tan(u + v)?

Back

tan(u + v) = (tanu + tanv) / (1 - (tanu)(tanv))

Front

What is the formula for tan(u - v)?

Back

tan(u - v) = (tanu - tanv) / (1 + (tanu)(tanv))

Front

What is the formula for cos(u + v)?

Back

cos(u + v) = (cosu)(cosv) - (sinu)(sinv)

Front

What is the formula for cos(u - v)?

Back

cos(u - v) = (cosu)(cosv) + (sinu)(sinv)

Front

What is the formula for sin(u + v)?
