What is the value of tan(a+b)?

I think we need more information such as what exactly is expected as an answer. For example, i could get
tab(a+b) = \(\displaystyle \frac{0.6 cos(a) + 0.5 cos(b)}{1-[0.6sin(a)+0.5sin(b)]}\)
or, choosing a number at random and allowed a choice of a and b
tan(a+b) = 7418.750712435
