Answer:

tan⁻¹ (a/b) - x

Step-by-step explanation:

Given:tan^{-1}[\frac{acosx-bsinx}{bcosx+asinx}]

Divide by bcosx, we get

=>tan^{-1}[\frac{\frac{acosx-bsinx}{bcosx}}{\frac{bcosx+asinx}{bcosx}}]

=>tan^{-1}[\frac{\frac{acosx}{bcosx}-\frac{bsinx}{bcosx}}{\frac{bcosx}{bcosx}+\frac{asinx}{bcosx}}]

=>tan^{-1}[\frac{\frac{a}{b}-tanx}{1+\frac{a}{b}tanx}]

=>tan^{-1}\frac{a}{b}-tan^{-1}(tanx)

=>\boxed{tan^{-1}\frac{a}{b} - x}}


Hope it helps!
