Find the length of the vector C starting from the components given in Equations 3 and 4.

Express C in terms of A, B, and theta.

2. Relevant equations

3. C_{x}= A + Bcos([tex]\theta[/tex]),

4. C_{y}= Bsin([tex]\theta[/tex]).

3. The attempt at a solution

C = [tex]\sqrt{C_x ^2+C_y ^2}[/tex]

C = [tex]\sqrt{A^2+(Bcos\theta)^2+(Bsin\theta)^2}[/tex]

using trig identity cos^{2}[tex]\theta[/tex]+sin^{2}[tex]\theta[/tex]=1

C = [tex]\sqrt{A^2+2B^2}[/tex] ???
