Question

se a graphing calculator to solve the equation in the interval from 0 to 2 π. Round to the nearest hundredth.7 cos (2t) =3

Answer 1

Given

$7cos\text{ \lparen2t\rparen=3}$$\begin{gathered} cos(2t)=\frac{3}{7} \\ \\ \end{gathered}$$\begin{gathered} 2t=1.128\text{ ,5.5.155} \\ divide\text{ by 2} \\ t=0.564,2.578 \end{gathered}$

The final answer

$t=0.56,\text{ 2.58}$
