							We know the expression for R=(A2+B2+2ABcos$\dpi{100} \theta$)½As A2 & B2 are positive and constant so the value of R will be Maximum when cos$\dpi{100} \theta$ is Maximum.Hence cos$\dpi{100} \theta$ is maximum at $\dpi{100} \theta$=0o so R is maximum at $\dpi{100} \theta$=0o.Similarly cos$\dpi{100} \theta$ is minimum at $\dpi{100} \theta$=180o so R is minimum at $\dpi{100} \theta$=180o.If you are helped by my solution then please approve the solution to encourage me.
