waves

Question: Two waves ${{y}_{1}}={{A}_{1}}\sin (\omega t-{{\beta }_{1}})$, ${{y}_{2}}={{A}_{2}}\sin (\omega t-{{\beta }_{2}})$ Superimpose to form a resultant wave whose amplitude is

1) $\sqrt{A_{1}^{2}+A_{2}^{2}+2{{A}_{1}}{{A}_{2}}\cos ({{\beta }_{1}}-{{\beta }_{2}})}$

2) $\sqrt{A_{1}^{2}+A_{2}^{2}+2{{A}_{1}}{{A}_{2}}\sin ({{\beta }_{1}}-{{\beta }_{2}})}$

3) ${{A}_{1}}+{{A}_{2}}$

4) $|{{A}_{1}}+{{A}_{2}}|$
