Sveta_85 [38]

Answer:

cos \frac{\theta}{2}= 0.894.

Step-by-step explanation:

Given:

cos\ \theta= \frac35

We need to find cos \ \frac{\theta}{2}

Solution:

cos\ \theta= \frac35

First we will find the value of \theta.

Now taking cos^{-1} on both side we get;

\theta= cos^{-1} \ \frac{3}{5}\\\\\theta = 53.13

Now we will find the \frac{\theta}{2}.

\frac{\theta}{2} = \frac{53.13}{2} = 26.565

Now we will find cos \ \frac{\theta}{2} we get;

cos \frac{\theta}{2}=cos\ 26.565 = 0.894

Hence cos \frac{\theta}{2}= 0.894.
