Hint:

$\mathrm{tan}\varphi =\frac{a}{b}$

$\frac{\mathrm{sin}\varphi}{a}=\frac{\mathrm{cos}\varphi}{b}=\pm \sqrt{\frac{?}{{a}^{2}+{b}^{2}}}$

Now replace the values of a,b

Now replace the values of a,b

Begin by assuming that

$a\mathrm{cos}\theta +b\mathrm{sin}\theta$

can be written in the form

$R\mathrm{sin}(x+\varphi )$

for some constants R and$\varphi$ . Expand the second expression using the angle addition formula, form some equations, and you should have it.
